by using the Cobolschemaexec utility. (The utility describes the

application’s understanding of data to the Pervasive PSQL relational

interface.) If a main table contains any REDEFINES layouts, you

must delete the REDEFINES tables before you can delete the main

table.

-3010: An OCCURS table with a mapping index to this

index exists. Cannot drop index

COBOL applications that include OCCURS, partial REDEFINES, or

variable record layout can enable SQL access to the Btrieve data files

by using the Cobolschemaexec utility. (The utility describes the

application’s understanding of data to the Pervasive PSQL relational

interface.) A main table can contain indexes to which an OCCURS

table can map. If an OCCURS table maps a main table index, you

cannot delete the main table index unless you first remove the

mapping from the OCCURS table.

-3011: A push-down filter has been defined on this

column. This column cannot be updated

COBOL applications that include OCCURS, partial REDEFINES, or

variable record layout can enable SQL access to the Btrieve data files

by using the Cobolschemaexec utility. (The utility describes the

application’s understanding of data to the Pervasive PSQL relational

interface.) A table can contain a logical expression associated with

the table. Such a table filter is referred to as a “push-down filter.”

You cannot update a column if it has a push-down filter defined it.

-3012: Only CREATE INDEX IN DICTIONARY operation is

supported for COBOL fake main table and variant records

COBOL applications that include OCCURS, partial REDEFINES, or

variable record layout can enable SQL access to the Btrieve data files

by using the Cobolschemaexec utility. (The utility describes the

application’s understanding of data to the Pervasive PSQL relational

interface.) You cannot perform a CREATE INDEX operation on a

variable record layout table unless you use the IN DICTIONARY

keyword (CREATE INDEX . . . IN DICTIONARY . . .).
