passing Sp parameter in the body at runtime in snowflake - snowflake-cloud-data-platform

Question

I have created a stored procedure to accept 2 parameters which helps to determine load type and based on that I am updating the control table to change dates.
When I am calling the SP it is failing due to:
Unexpected identifier in USP_NIGHTLYJOBRESETDAYS at
' ResetDaysDateRange = SELECT (`DATEADD(day,-?,DATEADD(day,DATEDIFF(day, '1900-01-01'::date, CURRENT_TIMESTAMP::date),'1900-01-01'::date))`,binds:[RESETDAYS]);' position 33
Here is the stored procedure code
CREATE OR REPLACE PROCEDURE etl.usp_NightlyJobResetDays (NIGHTLYLOAD VARCHAR(10), RESETDAYS VARCHAR(10))
RETURNS VARCHAR
LANGUAGE JAVASCRIPT
EXECUTE AS CALLER
AS
$$
var sql_command =
`BEGIN
let ResetDaysDateRange;
//Capturing date based on value
ResetDaysDateRange = SELECT (`DATEADD(day,-?,DATEADD(day,DATEDIFF(day, '1900-01-01'::date, CURRENT_TIMESTAMP::date),'1900-01-01'::date))`,binds:[RESETDAYS]);
//checking load type
if (NIGHTLYLOAD ='Yes')
{
EXEC(`Update Reporting.ReportingLoadDetail
SET MaxLoadDate = ?
WHERE IsNightlyLoadImpacted <> 'Yes'`,[ResetDaysDateRange]);
EXEC(`UPDATE Reporting.ReportingLoadDetail
SET MaxLoadDate = CASE WHEN ? > LastInitialLoadDate THEN ?
ELSE LastInitialLoadDate
END
WHERE IsNightlyLoadImpacted = 'Yes'`,[ResetDaysDateRange,ResetDaysDateRange]);
}
//reset restartabilityStatus to completed if last incremental load got failed
EXEC(`UPDATE etl.APILastLoadDetail set RestartabilityStatus = 'Completed'`);
END`
try {
snowflake.execute (
{sqlText: sql_command}
);
return "Succeeded."; // Return a success/error indicator.
}
catch (err) {
return "Failed: " + err; // Return a success/error indicator.
}
$$
;
//Calling sp
call etl.usp_NightlyJobResetDays('Yes',30);

Answer 1

something like this should work:
CREATE OR REPLACE PROCEDURE ETL.usp_NightlyJobResetDays (NIGHTLYLOAD VARCHAR(10), RESETDAYS VARCHAR(10))
RETURNS VARCHAR
LANGUAGE JAVASCRIPT
EXECUTE AS CALLER
AS
$$
try{
//Capturing date based on value
var sql_command1 = `SELECT TO_CHAR((DATEADD(day,-`+RESETDAYS+`,DATEADD(day,DATEDIFF(day, '1900-01-01'::date, CURRENT_TIMESTAMP::date),'1900-01-01'::date))))`;
var ResetDaysDateRange_res = snowflake.execute ({sqlText: sql_command1});
ResetDaysDateRange_res.next()
var ResetDaysDateRange = ResetDaysDateRange_res.getColumnValue(1);
//checking load type
if (NIGHTLYLOAD == `Yes`)
{
var sql_command2 = `Update Reporting.ReportingLoadDetail
SET MaxLoadDate = TO_DATE('`+ResetDaysDateRange+`')
WHERE IsNightlyLoadImpacted <> 'Yes'`;
snowflake.execute ({sqlText: sql_command2});
var sql_command3 = `UPDATE Reporting.ReportingLoadDetail
SET MaxLoadDate = CASE WHEN TO_DATE('`+ResetDaysDateRange+`') > LastInitialLoadDate THEN TO_DATE('`+ResetDaysDateRange+`')
ELSE LastInitialLoadDate
END
WHERE IsNightlyLoadImpacted = 'Yes'`;
snowflake.execute ({sqlText: sql_command3});
}
//reset restartabilityStatus to completed if last incremental load got failed
var sql_command4 = `UPDATE etl.APILastLoadDetail set RestartabilityStatus = 'Completed'`;
snowflake.execute ({sqlText: sql_command4});
return "Success";
}
catch (err) {
return "Failed: " + err; // Return a success/error indicator.
}
$$
;
