                             EnableCluster  | 
                        
                             Specifies whether clustered constraints are permitted on primary keys.  |

                             Determines whether a Create Index statement is generated for every Primary key statement. The following settings are available:

                             PKeyComment  |

                             UseSpPrimKey  | 
                        
                             Specifies the use of the Sp_primarykey statement to generate primary keys. For a database that supports the procedure to implement key definition, you can test the value of the corresponding variable %USE_SP_PKEY% and choose between the creation key in the table or launching a procedure. The following settings are available: Example (ASE 15): If UseSpPrimKey is enabled the Add entry for Pkey contains: UseSpPrimKey = YES Add entry of [%USE_SP_PKEY%?[execute] sp_primarykey %TABLE%, %PKEYCOLUMNS% :alter table [%QUALIFIER%]%TABLE% add [constraint %CONSTNAME%] primary key [%IsClustered%] (%PKEYCOLUMNS%) [%OPTIONS%]]  |
