Informix Alter Table Change Column Type
The RazorSQL alter table tool includes a Change Column Type option for changing the data types of columns on Informix database tables. The change column type function allows the user to choose a new type, a new length, and a new scale if appropriate for the data type chosen. The tool then generates the appropriate alter table alter column SQL command for changing the data type of the column on the table.
Listed below is an example of the SQL generated by the Informix Alter Table Change Column Type function:
ALTER TABLE sample:employee MODIFY (ssn char(25))
Below is a screen shot of the change column type function of the Informix alter table tool.
