Insert column could result in duplicate column references¶

What is new - 26.0¶

When the table structure of a database in use changes, the Check Database operation detects the modification and displays a dialog showing the stored table structure alongside the structure read from the database.

In some cases, newly added columns were not correctly detected by this process. Instead, a new column was automatically mapped to an existing column. The figure below illustrates this issue.

On the left, the stored table structure is shown; on the right, the updated table structure is displayed, with two columns highlighted in bold. This indicates that both columns are mapped to the same column in the data source.

This erroneous situation occurs when an inserted column has the same characteristics as the subsequent column.

As a result, referencing the newly added column later leads to a “symbol not defined” error.

This problem has now been fixed.
