1.8.5 Schema

These define the schema. You MUST either define them, or include library(cql/cql_autoschema) and add two directives to build the schema automatically:

• :-register_database_connection_details(+Schema, +ConnectionInfo).
• :-build_schema(+Schema).

Otherwise, you need to define at least cql:default_schema/1 and cql:dbms/2, and then as many of the other facts as needed for your schema.

• cql:default_schema(-Schema) MUST be defined. CQL autoschema will define this for you if you use it.
• cql:dbms(+Schema, -DBMS) MUST be defined for every schema you use. CQL autoschema will define this for you if you use it. DBMS must be one of the following:
  • 'Microsoft SQL Server'
  • 'PostgreSQL'
  • 'SQLite'

• cql:odbc_data_type(+Schema, +TableName, +ColumnName, +OdbcDataType).
• cql:primary_column_name(+Schema, +Tablename, +ColumnName).
• cql:database_attribute(+EntityType:table/view, +Schema:atom, +EntityName:atom, +ColumnName:atom, +DomainOrNativeType:atom, +AllowsNulls:allows_nulls(true/false), +IsIdentity:is_identity(true/false), +ColumnDefault).
• cql:database_domain(+DomainName, +OdbcDataType).
• cql:routine_return_type(+Schema, +RoutineName, +OdbcDataType).
• cql:database_constraint(+Schema, +EntityName, +ConstraintName, +Constraint).
