Column Names
Use the Column Names tab to set the template for the name of the newly created column.
The following tags are available:
{table_name} - the name of the table in which the column is created;
{table_schema} - the name of the schema that contains the table;
{num} - the ordinal number of a column with the same name;
{num_for_dup} - the number of a column which is applied if the column with the same name (without an ordinal number) already exists.
Click the tag to insert it at the cursor position.
