The gda-list-server-op-5.0 tool lists available DDL operations for one or all of the installed providers. For each type of operation (and each provider), the named parameters are also displayed. See the General words about DDL queries for more information about possible operations and usage. This tool has got several options, use the --help option to list them all.

For example listing all the possible operations (for all the providers) is:

[prompt]> gda-list-server-op-5.0 -l
Using XML descriptions in /usr/share/libgda-5.0
Existing operation types:
CREATE_DB
DROP_DB
CREATE_TABLE
DROP_TABLE
RENAME_TABLE
ADD_COLUMN
DROP_COLUMN
CREATE_INDEX
DROP_INDEX
	

Listing all the operations supported by the SQLite provider (notice that the SQLite provider does not support the DROP_COLUMN operation as SQLite does not support it):

[prompt]> gda-list-server-op-5.0 -l -p SQLite
Using XML descriptions in /usr/share/libgda-5.0
For provider SQLite
Existing operation types for provider 'SQLite':
CREATE_DB
DROP_DB
CREATE_TABLE
DROP_TABLE
RENAME_TABLE
ADD_COLUMN
CREATE_INDEX
DROP_INDEX
	

Listing all the possible parameters for the MySQL provider and for the DROP_COLUMN operation:

[prompt]> gda-list-server-op-5.0 -o DROP_COLUMN -p MySQL
Using XML descriptions in /usr/share/libgda-5.0
For provider MySQL
Description for type: DROP_COLUMN
<?xml version="1.0"?>
<server_op>
  <path id="/COLUMN_DESC_P" node_type="PARAMLIST" name="Column's description"/>
  <path id="/COLUMN_DESC_P/TABLE_NAME" node_type="PARAMETER" gdatype="gchararray" name="Table" descr="Table's name"/>
  <path id="/COLUMN_DESC_P/COLUMN_NAME" node_type="PARAMETER" gdatype="gchararray" name="Field name"/>
</server_op>
	

Listing all the possible parameters for the all the installed providers and for the DROP_COLUMN operation:

[prompt]> gda-list-server-op-5.0 -o DROP_COLUMN
