Limits on Query Text Size¶

Snowflake recommends you limit the size of query text (i.e. SQL statements) submitted through Snowflake clients to 1 MB per statement. Larger queries process normally, but you could not rerun or retry the larger queries, as Snowflake truncates queries larger than 1MB per statement before persisting them to the metadata store.

This limit includes any literals, such as string literals or binary literals, that are part of the statement, whether as part of a WHERE clause, SET clause (in an UPDATE statement), etc.

This limit also applies when binding values in client applications that use Snowflake connectors and drivers, such as the JDBC Driver.

If multiple SQL statements are combined into a single string (separated by semicolons), the length limit applies to the entire string, not to individual statements within the string.

Similarly, if data is batched, for example by using the JDBC PreparedStatement.addBatch() method, the entire batch must fit within the limit.

To load data that exceeds the limit, load from data files as described in Load data into Snowflake.
