I´m trying to get a result set of this statement
val sqlResult = ("Select max(dateInit) as Initial from table1)
val SQLDATE = (spark.read.format("jdbc").option("url", connSQLString).option("query", sqlREsult).option("user", useridSqlserver).option("password", passwordSqlserver).option("driver", jdbcSQLDriver).load())
var test1 = SQLDATE.show()
SQL is running fine and shows value, but my intention is to get the date from the result and put it in a variable to concat in another dynamic query.
thanks

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 am following the Snowflake Python Connector docs for variable binding to avoid SQL injection. I successfully set up a db connection with the following dict of credentials:
import snowflake.connector
CONN = snowflake.connector.connect(
user=snowflake_creds['user'],
password=snowflake_creds['password'],
account=snowflake_creds['account'],
warehouse=snowflake_creds["warehouse"],
database=snowflake_creds['database'],
schema=snowflake_creds['schema'],
)
cur = CONN.cursor(snowflake.connector.DictCursor)
The following block works fine and I get back query results, hard-coding the table name and using the standard format binding:
command = ("SELECT * FROM TEST_INPUT_TABLE WHERE batch_id = %s")
bind_params = (2)
results = cur.execute(command % bind_params).fetchall()
Similarly, this block works fine, using the pyformat binding:
command = ("SELECT * FROM TEST_INPUT_TABLE WHERE batch_id = %(id)s")
bind_params = {"id": 2}
results = cur.execute(command, bind_params).fetchall()
But the following two blocks both result in a ProgrammingError (pasted below the second block):
command = ("SELECT * FROM %s WHERE batch_id = %s")
bind_params = ("TEST_INPUT_TABLE", 2)
results = cur.execute(command, bind_params).fetchall()
command = ("SELECT * FROM %(tablename)s WHERE batch_id = %(id)s")
bind_params = {
"tablename": "TEST_INPUT_TABLE",
"id": 2
}
results = cur.execute(command, bind_params).fetchall()
ProgrammingError: 001011 (42601): SQL compilation error:
invalid URL prefix found in: 'TEST_INPUT_TABLE'
Is there some difference between how strings and ints get interpolated? I would
not think it would make a difference but that is all I can think of. Am I
missing something simple here? I don't want to have to choose between hard-coding the table name and putting the system at risk of SQL injection. Thanks for any guidance.
You should be wrapping your bind variables with an INDENTIFER() function when they reference an object, rather than a string literal. For example:
command = ("SELECT * FROM IDENTIFIER(%(tablename)s) WHERE batch_id = %(id)s")
https://docs.snowflake.com/en/sql-reference/identifier-literal.html
Give that a try.
I'm trying to update a two records with the same social in Classic ASP but I'm not sure how. This is what I have... but it don't update both records.
set rsTblEmpl=Server.CreateObject("ADODB.Recordset")
if 1=1 then
sql = "select * from tblEmpl where ssn=" & strSsn & ";"
else
sql = "select * from tblEmpl where eight_id=" & intEight_id & ";"
end if
rsTblEmpl.open sql, conn, 2, 3
if not rsTblEmpl.eof then
rsTblEmpl("posid") = StrPosId
rsTblEmpl("posname") = StrPosName
rsTblEmpl.update
end if
rsTblEmpl.close
set rsTblEmpl=nothing
The reason why it's only updating 1 value is because you're not looping over all records. You're only going to be updating the first record that it finds. So if there are multiple records with the same SSN you will have to change the if statement to a loop.
do until rsTblEmpl.eof
rsTblEmpl("posid") = StrPosId
rsTblEmpl("posname") = StrPosName
rsTblEmpl.update
rsTblEmpl.movenext
loop
Or you can do them all in one go using a parameterized UPDATE statement:
UPDATE tblEmpl SET posid = ?, posname = ? WHERE ssn = ?
The if 1=1 at the top I'll assume is a placeholder, because now it will always be true, so the else is not needed.
i have a table like this
DBName p_server_fqdn p_server_alias q_server_fqdn q_server_alias
cube1 server1.com p1server.com server5.com q1server.com
cube1 server2.com p1server.com server6.com q1server.com
cube2 server3.com p2server.com server7.com q2server.com
cube2 server4.com p2server.com server8.com q2server.com
I want to run a case select query in which i get the alias of a server input that matches a server column with corresponding DBName
this is what im trying so far
$SAlias = Invoke-sqlcmd -Query "SELECT DISTINCT CASE
WHEN ($cubeTable.DBName like $CUBE_input) AND ($cubeTable.p_server_fqdn) like $server_input THEN p_server_alias
WHEN ($cubeTable.DBName like $CUBE_input) AND ($cubeTable.q_server_fqdn) like $server_input THEN q_server_alias
ELSE 'unknown'
END as SAlias
FROM table $cubeTable" -ConnectionString "connectionstuff" | Select -ExpandProperty SAlias
but when i try the query itself in SSMS (with hardcoded values like cube1 and server2.com), i get back 2 rows with the row that dont match the DBName as "unknown" while 1 row shows p_server_alias
result im getting:
i should only get back the 1st row: p1server.com in this case, so why am i also getting unknown?
set #cubeInput = 'cube1';
set #serverInput = 'server6.com';
select
case when count(*) = 0 then 'UNKNOWN'
when m.p_server_fqdn = #serverInput then m.p_server_alias
when m.q_server_fqdn = #serverInput then m.q_server_alias
end as alias
from mytable m
where DBName = #cubeInput and (
p_server_fqdn = #serverInput
or q_server_fqdn = #serverInput
);
here is the implementation of my answer : http://sqlfiddle.com/#!9/b967a22/61
#Cataster solution return 2 rows becouse actualy he get 4 rows (3 rows 'unkown' and 1 row 'p1server.com') then he put distinct in the query. it's make result become 2 rows.
my solution little bit tricky :). Using filter in the query. than if we get no row as the result use the count function. So we get 1 row and the value is 0 than show it as 'UNKNOWN'.
I have MS SQL Server stored procedure (SQL Server 2012) which returns:
return value describing procedure execution result in general (successfull or not) with return #RetCode statement (RetCode is int type)
one result set (several records with 5 fields each)
another result set (several records with 3 fields each)
I calling this procedure from my Groovy (and Java) code using Java's CallableStatement object and I cannot find right way to handle all three outputs.
My last attempt is
CallableStatement proc = connection.prepareCall("{ ? = call Procedure_Name($param_1, $param_2)}")
proc.registerOutParameter(1, Types.INTEGER)
boolean result = proc.execute()
int returnValue = proc.getInt(1)
println(returnValue)
while(result){
ResultSet rs = proc.getResultSet()
println("rs")
result = proc.getMoreResults()
}
And now I get exception:
Output parameters have not yet been processed. Call getMoreResults()
I tried several approaches for some hours but didn't find correct one. Some others produced another exceptions.
Could you please help me with the issue?
Thanks In Advance!
Update (for Tim):
I see rc while I launched code:
Connection connection = dbGetter().connection
CallableStatement proc = connection.prepareCall("{ ? = call Procedure_Name($param_1, $param_2)}")
boolean result = proc.execute()
while(result){
ResultSet rs = proc.getResultSet()
println(rs)
result = proc.getMoreResults()
}
I see rc as object: net.sourceforge.jtds.jdbc.JtdsResultSet#1937bc8
