U0520001: The SMALLDATETIME data type in SQL Server is accurate to minute, while the TIMESTAMP (0) data type in PostgreSQL is accurate to second

Description

Database Type and Version

  • Source database type and version: all SQL Server versions
  • Target database type and version: all PostgreSQL versions

Syntax Example

In SQL Server, the SMALLDATETIME data type does not map to another type in PostgreSQL. UGO uses TIMESTAMP (0) for conversion and displays the precision difference between the two types. For example:

SQL Server syntax:

CREATE TABLE tab(c1 SMALLDATETIME);

Suggestion

Check whether the UGO conversion solution meets service and application requirements or modify the data type.
