I need to snowflake how to create dummy stored procedure with out put array as push in snowflake.
Dummy stored procedure using Snowflake Scripting:
CREATE PROCEDURE dummy()
RETURNS ARRAY
LANGUAGE SQL
AS
$$
begin
return ARRAY_CONSTRUCT(1,2,3);
end;
$$;
CALL dummy();
-- [ 1, 2, 3 ]
DESC RESULT LAST_QUERY_ID();
-- name type kind
-- DUMMY ARRAY COLUMN
Since you mentioned pushing to the array, I'll add to Lukasz's answer to show a JavaScript example with pushing to the array in a loop:
create or replace procedure ARRAY_SAMPLE()
returns array
language javascript
as
$$
var arr = [];
var rs = snowflake.execute({sqlText:'select N_NAME from SNOWFLAKE_SAMPLE_DATA.TPCH_SF1.NATION'});
while (rs.next()) {
arr.push(rs.getColumnValue('N_NAME'));
}
return arr;
$$;
call ARRAY_SAMPLE();
CREATE OR ALTER FUNCTION sso.FINDSEQVALUE
(#sequence_text text)
RETURNS int
AS
BEGIN
DECLARE #value int;
DECLARE #sequence_value nvarchar(150);
SELECT #sequence_value = CAST(#sequence_text AS nvarchar(150));
SELECT #value = NEXT VALUE FOR #sequence_value;
RETURN #value;
END;
I have a problem. I have created a function on SQL Server and I defined the parameter as you can see. But I cannot add the this command #sequence_value after NEXT VALUE FOR command and I am getting an error.
Incorrect syntax near '#sequence_value'
Somebody can say that "You can use (SELECT NEXT VALUE FOR [SEQUENCE])". But I need this function because of there are two different database on my project. I need same function for databases. In addition function parameter need to be text.
What should I do?
I have to add a variable MaxDate in my SQL Stored Proc (shown below). The code gets errored out since MaxDate is not represented by its value. Any idea on how I can pass a variable in a stored proc?
create or replace procedure Load_Employee()
returns varchar not null
language javascript
EXECUTE AS CALLER
as
$$
//Variable Initialization
var IntegrationTable ='EMPLOYEE';
var TypeID=0;
var MaxDate=' ';
var cmd = "Select max(COMPLETED_DATE) from SCHEMA.TABLE where TARGET_TABLE_NAME= " + "'" + IntegrationTable + "'" ;
var sql = snowflake.createStatement({sqlText: cmd});
var result = sql.execute();
result.next();
MaxDate=result.getColumnValue(1);
var cmd=` Insert into PersonTable
select SHA1(concat(Person_id,'|','Person')) ,12345678,SHA1(concat('Payroll','|','Pay','|', Load_Date)) ,current_timestamp() , Tenant
from Schema.PERSONTABLE where Date_Added >= MaxDate
where TYPE='ABC' ;`;
$$
;
If your query to get MaxDate works right, then the value should be in the variable. The problem is it's not being replaced in the sql variable defining the insert statement.
Since you're using backticks to open and close the string, you can use a special JavaScript notation to replace the variable with its value, ${MaxDate}.
Your definition of the insert statement would look like this:
var cmd=` Insert into PersonTable
select SHA1(concat(Person_id,'|','Person')) ,12345678,SHA1(concat('Payroll','|','Pay','|', Load_Date)) ,current_timestamp() , Tenant
from Schema.PERSONTABLE where Date_Added >= ${MaxDate}
where TYPE='ABC' ;`;
If that doesn't work, try cutting the SP short with return MaxDate; to see what got assigned to that variable. Also it's very helpful to check the query history view to see what SQL actually ran inside a stored procedure.
Also, I think this is the same SP that was having an issue with a null return. You'll need to return a string value using something like return 'Success'; or something to avoid getting an error for the null return. That's because of the returns varchar not null in the definition.
I have a stored procedure that works fine but it has inside it three "select"s.
The selects are not from an inner temporary table.
This is mainly the format of the procedure:
ALTER PROCEDURE [dbo].[STProce]
#param1 int,
#param2 int,
#param3 int,
#param4 int,
#param5 int
AS
select #param1 as p1, #param2 as p2, #param3 as p3
.
.
.
select #param4 as p4
.
.
.
select #param5 as p5
I'm executing the procedure from another procedure and need to catch it there.
I created a table and inserts into it the "exec" from the procedure, like that:
CREATE TABLE #stalledp
(
RowNumber INT,
fldid INT,
fldLastUpdated datetime,
fldCreationDate datetime,
fldName nvarchar(255),
fldPending nvarchar(255)
)
INSERT INTO #stalledp (RowNumber,fldid,fldLastUpdated,fldCreationDate,fldName,fldPending)
EXEC spDebuggerViews_GetStuckWorkflowInstances #workflowSpaceId='00000000-0000-0000-0000-000000000000',#pageNum=1,#pageSize=100000,#orderByColumn=N'fldid',#sortOrder=1,#workflowInstanceId=0,#stuckInstanceType=1,#createdDateFrom='1900-01-01 00:00:00',#createdDateTo='9999-01-01 23:59:59',#updatedDateFrom='1900-01-01 00:00:00',#updatedDateTo='9999-01-01 23:59:59'
Afterwards I receive this error:
Column name or number of supplied values does not match table definition.
The order and name of columns of the table is exactly like the procedure returns.
Is there a possibility to catch only one of the tables that the procedure returns and avoid the other? I cannot change the procedure at all.
I tried declaring a table the same fields as the first select of the procedure and I get an error says that
Thank you in advance!
If all of the result sets returned are of the same structure, then you can dump them to a temp table as you are trying to do. However, that only gets you so far because if the data in the fields cannot be used to determine which result set a particular row came from, then you just have all of the result sets with no way to filter out the ones you don't want.
The only way to interact with multiple result sets individually, regardless of them having the same or differing structures, is through app code (i.e. a client connection). And if you want to do this within the context of another query, then you need to use SQLCLR.
The C# code below shows a SQLCLR stored procedure that will execute a T-SQL stored procedure that returns 4 result sets. It skips the first 2 result sets and only returns the 3rd result set. This allows the SQLCLR stored procedure to be used in an INSERT...EXEC as desired.
The code for the T-SQL stored proc that is called by the following code is shown below the C# code block. The T-SQL test proc executes sp_who2 and only return a subset of the fields being returned by that proc, showing that you don't need to return the exact same result set that you are reading; it can be manipulated in transit.
C# SQLCLR proc:
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
public class TheProc
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void Get3rdResultSetFromGetStuckWorkflowInstances()
{
int _ResultSetsToSkip = 2; // we want the 3rd result set
SqlConnection _Connection = null;
SqlCommand _Command = null;
SqlDataReader _Reader = null;
try
{
_Connection = new SqlConnection("Context Connection = true;");
_Command = _Connection.CreateCommand();
_Command.CommandType = CommandType.StoredProcedure;
_Command.CommandText = "tempdb.dbo.MultiResultSetTest";
// (optional) add parameters (but don't use AddWithValue!)
// The SqlDataRecord will be used to define the result set structure
// and act as a container for each row to be returned
SqlDataRecord _ResultSet = new SqlDataRecord(
new SqlMetaData[]
{
new SqlMetaData("SPID", SqlDbType.Char, 5),
new SqlMetaData("Status", SqlDbType.NVarChar, 30),
new SqlMetaData("Login", SqlDbType.NVarChar, 128),
new SqlMetaData("HostName", SqlDbType.NVarChar, 128),
new SqlMetaData("BlkBy", SqlDbType.VarChar, 5),
new SqlMetaData("DBName", SqlDbType.NVarChar, 128)
});
SqlContext.Pipe.SendResultsStart(_ResultSet); // initialize result set
_Connection.Open();
_Reader = _Command.ExecuteReader();
// Skip a predefined number of result sets
for (int _Index = 0;
_Index < _ResultSetsToSkip && _Reader.NextResult();
_Index++) ;
// Container used to move 1 full row from the result set being read
// to the one being sent, sized to the number of fields being read
Object[] _TempRow = new Object[_Reader.FieldCount];
while (_Reader.Read())
{
_Reader.GetValues(_TempRow); // read all columns
_ResultSet.SetValues(_TempRow); // set all columns
SqlContext.Pipe.SendResultsRow(_ResultSet); // send row
}
}
catch
{
throw;
}
finally
{
if(SqlContext.Pipe.IsSendingResults)
{
SqlContext.Pipe.SendResultsEnd(); // close out result set being sent
}
if(_Reader != null && !_Reader.IsClosed)
{
_Reader.Dispose();
}
_Command.Dispose();
if (_Connection != null && _Connection.State != ConnectionState.Closed)
{
_Connection.Dispose();
}
}
return;
}
}
T-SQL test proc:
USE [tempdb]
SET ANSI_NULLS ON;
IF (OBJECT_ID('dbo.MultiResultSetTest') IS NOT NULL)
BEGIN
DROP PROCEDURE dbo.MultiResultSetTest;
END;
GO
CREATE PROCEDURE dbo.MultiResultSetTest
AS
SET NOCOUNT ON;
SELECT 1 AS [ResultSet], 'asa' AS [test];
SELECT 2 AS [ResultSet], NEWID() AS [SomeGUID], GETDATE() AS [RightNow];
EXEC sp_who2;
SELECT 4 AS [ResultSet], CONVERT(MONEY, 131.12) AS [CashYo];
GO
EXEC tempdb.dbo.MultiResultSetTest;
To do:
Adjust _ResultSetsToSkip as appropriate. If you only want the first result set, simply remove both _ResultSetsToSkip and the for loop.
Define _ResultSet as appropriate
Set _Command.CommandText to be "spDebuggerViews_GetStuckWorkflowInstances"
Create the necessary parameters via SqlParameter (i.e. #workflowSpaceId='00000000-0000-0000-0000-000000000000',#pageNum=1,#pageSize=100000,#orderByColumn=N'fldid',#sortOrder=1,#workflowInstanceId=0,#stuckInstanceType=1,#createdDateFrom='1900-01-01 00:00:00',#createdDateTo='9999-01-01 23:59:59',#updatedDateFrom='1900-01-01 00:00:00',#updatedDateTo='9999-01-01 23:59:59')
If needed, add input parameters to the SQLCLR proc so that they can be used to set the values of certain SqlParameters
Then use as follows:
INSERT INTO #stalledp
(RowNumber,fldid,fldLastUpdated,fldCreationDate,fldName,fldPending)
EXEC Get3rdResultSetFromGetStuckWorkflowInstances;
There is a way to get the first record set but the others, I'm afraid, you're out of luck.
EXEC sp_addlinkedserver #server = 'LOCALSERVER', #srvproduct = '',
#provider = 'SQLOLEDB', #datasrc = ##servername
SELECT * FROM OPENQUERY(LOCALSERVER, 'EXEC testproc2')
EDIT: If you only need to check the other result set for columns to be not null you could predefine the expected results sets like so:
EXEC testproc2 WITH RESULT SETS (
(a VARCHAR(MAX) NOT NULL, b VARCHAR(MAX) NOT NULL),
(a VARCHAR(MAX) NOT NULL)
);
If the query within the stored procedure returns null values a exception is raised at that point in procedure. This will only work on sql server 2012 and upwards though.
Below is the SQL Server's syntax to select variable as a record
DECLARE #number AS INTEGER;
SET #number = 10;
SELECT #number;
How can I do this in ORACLE?
Thanks in advance.

Edited based on comment:
One way you can access the variable value assigned by a procedure is through a function again.
Example:
CREATE OR REPLACE PROCEDURE your_procedure(out_number OUT number)
IS
BEGIN
out_number:=1;
END;
function to retrieve the procedure's output
CREATE OR REPLACE FUNCTION your_function
RETURN number
AS
o_param number;
BEGIN
o_param := NULL;
your_procedure(o_param);
RETURN o_param;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
return 0; --basically how you want to handle your errors.
END your_function;
Now you can select the output of the procedure
select your_function from dual;
Useful link how to access an Oracle procedure's OUT parameter when calling it?
If you are trying to create a variable to access anywhere in your application in oracle.
You can do it by creating function and calling it from dual.
SQL>create or replace function foo return number
as
x number;
begin
x:=1;
return 1;
end;
Function created.
SQL>select foo from dual;
