I can retrieve the values of before(0) and after counts(4) from the below statements, but when I make use of those variables (load_cnt_before, load_cnt_after) from the code below and refer them to have the values inserted into a table it says it cant find the variables(refer to error below). How can I use those values to INSERT them into table.
Error: Execution error in stored procedure REC_COUNT_CHECK: SQL compilation error: error line 1 at position 114 invalid identifier 'LOAD_CNT_BEFORE' At Statement.execute, line 25 position 90
Code:

JS variables should be passed into SQL query. The mechanism is called Binding Variables

var exec_sp1_status = snowflake.createStatement(

var run_id_query = `INSERT INTO STG.RUN_STATUS (RUNID,STATUS,STATUS_DESCRIPTION)

insert is present in STG schema, i am trying to insert it from INT schema
Could you break it down e.g.:
run_id_query = $$INSERT INTO STG.RUN_STATUS (RUNID,STATUS,STATUS_DESCRIPTION) VALUES (TO_CHAR(CURRENT_DATE,'YYYYMMDD'),0,'RUN START')$$;
execute immediate $run_id_query
I am trying to create a Procedure in snowflake.
CREATE OR REPLACE PROCEDURE test()
returns string not null language javascript as
$$
var cmd = "select count(1) from Test1.table1";
var sql = snowflake.createStatement({sqlText: cmd});
var result = sql.execute();
return '1';
$$;
"table1" existing in schema "schema1" but i am trying to create this procedure in schema2. schema2 does have an access to "table1.
when I run the same query in snowflake web UI with schema "schema2" where i am creating the procedure select count(1) from Test1.table1 it is working but inside procedure it is not working and displaying me error
schema does not exist and not authorized
CREATE OR REPLACE PROCEDURE test()
returns string not null language javascript as
$$
var cmd = "select count(1) from Test1.table1";
var sql = snowflake.createStatement({sqlText: cmd});
var result = sql.execute();
return '1';
$$;
if you fully qualify you names, things just work:
use schema test.test;
create schema test.test1;
create table test.test1.table1(id int);
CREATE OR REPLACE PROCEDURE test.test1.test()
returns string not null language javascript as
$$
var cmd = "select count(1) from test.test1.table1";
var sql = snowflake.createStatement({sqlText: cmd});
var result = sql.execute();
return '1';
$$;
call test.test1.test();
TEST
1
create schema test.test2;
use schema test.test2;
call test.test1.test();
TEST
1
use schema test.test2;
CREATE OR REPLACE PROCEDURE test.test2.test()
returns string not null language javascript as
$$
var cmd = "select count(1) from test.test1.table1";
var sql = snowflake.createStatement({sqlText: cmd});
var result = sql.execute();
return 'called table1 from schema2';
$$;
call test.test2.test();
TEST
called table1 from schema2
So why your error?
The below SQL I have made non fully qualified. So the function will be in the current scehma. Which for me is test.test2. But now I am referring to schema schema1.table1 and schema1 does not exist. thus the error message when I run the code.
CREATE OR REPLACE PROCEDURE test()
returns string not null language javascript as
$$
var cmd = "select count(1) from schema1.table1";
var sql = snowflake.createStatement({sqlText: cmd});
var result = sql.execute();
return 'called table1 from schema2';
$$;
call test.test2.test();
gives:
SQL compilation error:
Schema 'TEST.SCHEMA1' does not exist or not authorized.
At Statement.execute, line 4 position 21
The other possible outcome is you have the function defined as EXECUTE AS OWNER and the two functions do have two different owners, with different owning permissions. But I am going to doubt that.
I am creating snowflake JavaScript based store procedure. How can i refer the date data type variable in snowflake sql.
Here is the sample code:
In the below code ,please suggest how can i use 'dnblatestdt' variable in sql statement.
create or replace procedure test_proc_registration_master_perished_dt(PARAM_REG_SUB_UUID VARCHAR)
returns varchar not null
language javascript
as
$$
/*get latest ingestion_uuid for the given state*/
var step01=`select distinct dnb_applicable_dt,ingestion_uuid from temp_registration_hash_master `;
var statement01=snowflake.createStatement( {sqlText: step01,binds: [PARAM_REG_SUB_UUID]} );
variable1= statement01.execute();
variable1.next();
dnblatestdt=variable1.getColumnValue(1);
ingsuuid=variable1.getColumnValue(2);
/* check if the ingestion is successful or not*/
var step02=`select INGESTION_SUCCESSFUL from FILE_INGESTION_HISTORY where ingestion_uuid=:1 and date=:2::TIMESTAMP_LTZ::DATE`;
var statement02=snowflake.createStatement( {sqlText: step02,binds: [ingsuuid,dnblatestdt]} );
variable2= statement02.execute();
variable2.next();
ingsindc=variable2.getColumnValue(1);
return 'success'
$$
So I wrote a much simpler function that uses a similar pattern to your code:
create or replace procedure test_proc()
returns varchar not null
language javascript
as
$$
var step01 = `SELECT 6::number, '2022-01-27'::timestamp_ntz;`;
var statement01 = snowflake.createStatement( {sqlText: step01} );
results1 = statement01.execute();
results1.next();
ingsuuid = results1.getColumnValue(1);
dnblatestdt = results1.getColumnValue(2);
/* check if the ingestion is successful or not*/
var step02=`SELECT :1 * 2, DATEADD(year,-1, :2::timestamp_ntz);`;
var statement02 = snowflake.createStatement( {sqlText: step02,binds: [ingsuuid , dnblatestdt]} );
results2 = statement02.execute();
results2.next();
ingsindc = results2.getColumnValue(1);
return 'success'
$$
;
and using it works for me:
call test_proc();
TEST_PROC
success
I swapped the order of the reading parameters on the first function, but that should not be a problem.
this makes me thing your casting on the second instance is not working
:2::TIMESTAMP_LTZ::DATE
so I would suggest moving that casting to the first function, which you can test outside the stored procedure, thus.
SELECT DISTINCT dnb_applicable_dt::TIMESTAMP_LTZ::DATE, ingestion_uuid
FROM temp_registration_hash_master
when that is happy, you shouldn't need any casting on the second used of the values.
I compiled a stored procedure but I'm unable to execute it - getting this error:
Execution error in stored procedure SAMPLE_ETL_MONITORING_PROC: Stored procedure execution error: Requested information on the current user is not accessible in stored procedure. At Statement.execute, line 18 position 45
I have write access to the database but not sure If I have to include any commands/statements in the script. Can anyone please suggest what needs to be done?
Here is the script:
CREATE OR REPLACE PROCEDURE sample_etl_monitoring_proc()
returns string not null
language javascript
as
$$
var insert_cmd = `
truncate table OOBE.monitoring.load_history_1
`
var sql_insert = snowflake.createStatement({sqlText: insert_cmd});
var insert_result = sql_insert.execute();
var stream_select_cmd = `
insert into OOBE.monitoring.load_history_1
select * from (
select * from OOBE.information_schema.load_history
union
select * from snowplow.information_schema.load_history);
`
var sql_select_stream = snowflake.createStatement({sqlText: stream_select_cmd});
var select_stream_result = sql_select_stream.execute();
return '👍';
$$;
I reproduced the error and got this to work by adding an explicit caller's right declaration:
CREATE OR REPLACE PROCEDURE sample_etl_monitoring_proc()
returns string not null
language javascript
execute as caller

I have just learned about Streams and Tasks in Snowflake and have tested the example for tracking members and sign ups in the first example here.
I have attempted to create a stored procedure that looks like this:
CREATE OR REPLACE procedure member_update()
returns string not null
language javascript
as
$$
var statement = snowflake.createStatement({sqlText: "BEGIN"} );
statement.execute();
var statement = snowflake.createStatement({sqlText: "UPDATE members SET fee = fee + 15 where fee > 0"} );
statement.execute();
var statement = snowflake.createStatement({sqlText: "SELECT * FROM member_check"} );
statement.execute();
var statement = snowflake.createStatement({sqlText: "COMMIT"} );
statement.execute();
var statement = snowflake.createStatement({sqlText: "SELECT * FROM member_check"} );
statement.execute();
$$
;
INSERT INTO members (id,name,fee)
VALUES
(11,'Bill',0),
(12,'Jason',0),
(13,'Suzan',0),
(14,'Michelle',0),
(15,'AARON',0);
SELECT * FROM MEMBER_CHECK;
INSERT INTO signup
VALUES
(11,'2018-01-01'),
(12,'2018-02-15'),
(13,'2018-05-01'),
(14,'2018-07-16'),
(15,'2018-08-21');
MERGE INTO members m
USING (
SELECT id, dt
FROM signup s
WHERE DATEDIFF(day, '2018-08-15'::date, s.dt::DATE) < -30) s
ON m.id = s.id
WHEN MATCHED THEN UPDATE SET m.fee = 90;
Call member_update();
I have run into an error and was hoping I might get some guidance on by very beginner stored procedure.
Error:
Execution error in store procedure MEMBER_UPDATE: empty argument
