Unable to Call a Snowflake procedure with a Data Governance tool Called Ataccama

Question

I am using a data governance too called ATaccama and I have created a SP in Snowflake but I am getting below error when I am calling the SP from Ataccama JDBC sql execute component. However, I am using latest JDBC driver for SNOWFLAKE : snowflake-jdbc-3.9.2. Your help is much appreciated!

ERROR:
net.snowflake.client.jdbc.SnowflakeSQLException: Statement 'call PII.kc11_search...' cannot be executed using current API.

[NOTE: using - Call PII. Kc11_seach().]

Any ideas or otherwise beneficial recommendations?

Answer 1

The Snowflake JDBC driver does not currently support executing any SQL statements that may return a value as part of its PreparedStatement::executeBatch(…) call that Attacama is using under the hood. This is because the batch call handling cannot process returned values from one or more of their multiple executed SQL queries.

Since a CALL PROCEDURE() may return a value, the driver considers it as a statement that may generate a result and throws the unsupported statement error.

To call a procedure via Attacama, use a different component that does not use JDBC's PreparedStatement::executeBatch(…) calls underneath.
