SQL Create Table |
|
The Generate SQL Create Table Commands utility simplifies the process of converting the data dictionary to a SQL-based database such as ORACLE or Microsoft SQL. The utility outputs CREATE TABLE directives for defining database tables that are consistent with the PxPlus data dictionary. By default, this output includes all the fields within a table definition, including fields in non-normalized tables.
In the case of non-normalized files, duplicate element names are output once, and the first occurrence of the element name defines the element's format. Table Index definitions will also be created using either the Key name as supplied in the Data Dictionary definition or a generated name based on the Table Name followed by an underscore and key number. The Generate button outputs the CREATE statements to the utility window for viewing.
Invoke the Generate SQL Create Table Commands utility by selecting Utilities > Generate external > SQL Create Table from the Data Dictionary Maintenance menu bar.
This utility consists of the following:
|
Table Name |
Click the Query Table View button (magnifying glass) for a tree view of table names by Group. For information on creating a filter to locate a specific table name, see Filtering the Table Names Lookup. |

|
Copy to Clipboard |
