How to work with the DDL data source

Step 1. Define a table in an SQL file

In the Files tool window (View | Tool Windows | Files), right-click a directory and select New | SQL File. Specify a name for the SQL file.

Open the SQL file and define the following table structure in our file:

1. For inserting the CREATE TABLE statement, there is a predefined pattern. Press Control+J and select the pattern tab - new table definition.

   

   Here is the result:

   

2. Type the table name family.

   

3. To switch from family to col, press Tab. Replace col with member_id.

   

4. Type the remaining part of the table definition.

   

Step 2. Create a DDL data source from the SQL file

To create a table from the SQL file, drag the SQL file with the defined table to the Database Explorer ( View | Tool Windows | Database Explorer).

Step 3. Define data for the data source

Now we are going to create an SQL file for adding data to the table. On Step 2, the SQL file was defined as a data source, the names of the table and of its columns as well as the info about corresponding data types are now available in the editor.

1. Create an SQL file.

   

   Let us add this simple INSERT statement into the file:

   insert into family (member_id, name, relation) values (1, 'Chloe', 'mother');

2. Add the INSERT statement by selecting the corresponding predefined pattern: Control+J | ins - insert rows into a table.

   

3. Select the table name family.

   

4. Select the list of column names member_id, name, relation.

   

5. When specifying the values, press Control+P (View | Parameter Info) to see the information about the value types.
