Sybase ASA to SQL Server For more information, see Snowpark Package Types Supported for User-Defined Functions. For example, INTEGER data can be converted to DECIMAL when writing to Snowflake, because INTEGER and DECIMAL are semantically equivalent in Snowflake (see Snowflake Numeric Data Types ). The connector utilizes Snowflake internal data transfer. Moving data out of a warehouse is a less-conventional approach, but sometimes it's necessary. This precision can lie in the range of 0 (seconds) to 9 (nanoseconds). The following statement coerces the INTEGER value in column my_integer_column to FLOAT so that the value can be Formats the time as HH:MI:SS.SSSSSSSSS where the fractional seconds part depends on the precision of the time.
