Setting preferences for SQL retrieve

At EGL declaration time, you can use the SQL retrieve feature to create an SQL record from the columns of an SQL table.
To set preferences for the SQL retrieve feature:
  1. Select Window > Preferences, expand EGL and then click SQL
  2. Specify the rules for creating each structure field that the SQL retrieve feature creates:
    1. To specify the EGL type to use when you create a record field from an SQL character data type, select one of the following radio buttons:
      • Use EGL type string: (the default) maps SQL char data types to EGL string data types
      • Use EGL type limited-length string: maps SQL char data types to EGL limited-length string data types
      • Use EGL type char: maps SQL char data types to EGL char data types
      • Use EGL type mbChar: maps SQL char data types to EGL mbChar data types
      • Use EGL type Unicode: maps SQL char data types to EGL Unicode data types
    2. To specify the EGL type to use when you create a record field from an SQL national character data type, select one of the following radio buttons:
      • Use EGL type dbChar: (the default) maps the SQL type to EGL dbChar data types
      • Use EGL type Unicode: maps the SQL type to EGL Unicode data types
      • Use EGL type string: maps the SQL type to EGL string data types
      • Use EGL type limited-length string: maps the SQL type to EGL limited-length string data types
    3. To specify the case of the record field name, select one of the following radio buttons:
      • Do not change case: (the default) the case of the structure field name is the same as the case of the related table column name
      • Change to lower case: the structure field name is a lowercase version of the table column name
      • Change to lower case and capitalize first letter after underscore: the structure field name is a lower-case version of the table column name; however, a letter in the structure field name is rendered in uppercase if, in the table column name, the letter immediately follows an underscore
    4. To specify how the underscores in the table column name are reflected in the record field name, select one of the following radio buttons:
      • Do not change underscores: (the default) underscores in the table column name are included in the structure field name
      • Remove underscores: underscores in the table column name are not included in the structure field name
  3. If you want new SQL records to be compatible with COBOL programs (that is, to have fixed records with level numbers for structure items, and to use CHAR instead of STRING primitive types), select Add level numbers to record definition.
  4. If you want new SQL records to have the key field property set, select Retrieve primary key information from the system catalog.
  5. If you want to be prompted for a database password if you did not supply one for the connection on the SQL Database Connections page, select Prompt for SQL user ID and password when needed.
  6. To save your changes and remain in the Preferences window, click Apply. To save your changes and exit the window, click OK.
