In this video, I am going to talk about what is the generator in snowflake. Generator Table Function 1) Creates rows of data based either on a specified number of rows, a specified generation period (in seconds), or both. 2) This Generator system-defined table function enables synthetic row generation. Usage Notes: count and sec must be non-negative integer constants. If only the ROWCOUNT argument is specified, the resulting table will contain count rows. If only the TIMELIMIT argument is specified, the query runs for sec seconds, generating as many rows as possible within the time frame. If both the ROWCOUNT and TIMELIMIT arguments are specified, then: If the ROWCOUNT is reached before the TIMELIMIT, the resulting table will contain count rows. If the TIMELIMIT is reached before the ROWCOUNT, the table will contain the number of rows generated within the time frame. If ROWCOUNT or TIMELIMIT is null, it will be ignored. So generator(ROWCOUNT = null) generates 0 rows. If both parameters (ROWCOUNT and TIMELIMIT) are omitted, the GENERATOR function returns 0 rows. #snowflake#datacloud#datapipeline#vcklytech
