Create a DDL data source using SQL files
DDL data source is a virtual view of a database structure based on SQL files that contain data definition language statements (DDL statements). You can reference all tables, columns and other objects defined in such files in the editor. Diagrams are also supported.
To create a DDL data source using SQL files, create new SQL files that contain the required statements to define database objects and data for the data source.
For more information about DDL data sources, refer to the DDL data sources topic.
Step 1. Define a table in an SQL file
In the In the Files tool window ( ) , right-click a directory and select . Specify a name for the SQL file.
Open the SQL file and define the following table structure in our file:
For inserting the
CREATE TABLEstatement, there is a predefined pattern. Press Control+J and select the pattern
tab - new table definition.
Type the table name
To switch from
col, press Tab. Replace
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 ( ) .
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.
Create an SQL file.
let's add this simple
INSERTstatement into the file:insert into family (member_id, name, relation) values (1, 'Chloe', 'mother');
INSERTstatement by selecting the corresponding predefined pattern: Control+J |
ins - insert rows into a table.
Select the table name
Select the list of column names
member_id, name, relation.
When specifying the values, press Control+P () to see the information about the value types.
