SQL Table Name: INFORMATION_SCHEMA.TABLE_CONSTRAINTS
Returns one row for each table constraint in the current namespace for tables that can be accessed by the current user in the current namespace.Property Inventory
- CONSTRAINTCATALOG
- CONSTRAINTNAME
- CONSTRAINTSCHEMA
- CONSTRAINTTYPE
- INITIALLYDEFERRED
- ISDEFERRABLE
- TABLECATALOG
- TABLENAME
- TABLESCHEMA
Parameters
parameter READONLY = 1;
Inherited description: READONLY = 1 means that objects can be created, opened but not saved or deleted.
Tables are projected to SQL as READONLY.
Properties
property CONSTRAINTCATALOG as %String (MAXLEN = 128) [ Calculated , SqlFieldName = CONSTRAINT_CATALOG ];
Table qualifier - always NULL in InterSystems IRIS.
Property methods: CONSTRAINTCATALOGCompute(), CONSTRAINTCATALOGDisplayToLogical(), CONSTRAINTCATALOGGet(), CONSTRAINTCATALOGIsValid(), CONSTRAINTCATALOGLogicalToDisplay(), CONSTRAINTCATALOGLogicalToOdbc(), CONSTRAINTCATALOGNormalize(), CONSTRAINTCATALOGSQLCompute()
property CONSTRAINTNAME as %String (COLLATION = "Upper", MAXLEN = 128) [ SqlFieldName = CONSTRAINT_NAME , Required ];
Name of the constraint.
Property methods: CONSTRAINTNAMEDisplayToLogical(), CONSTRAINTNAMEGet(), CONSTRAINTNAMEIsValid(), CONSTRAINTNAMELogicalToDisplay(), CONSTRAINTNAMELogicalToOdbc(), CONSTRAINTNAMENormalize(), CONSTRAINTNAMESet()
property CONSTRAINTSCHEMA as %String (COLLATION = "Upper", MAXLEN = 128) [ Calculated , SqlFieldName = CONSTRAINT_SCHEMA ];
Name of schema that contains the constraint. Always the same as the TABLE_SCHEMA.
Property methods: CONSTRAINTSCHEMACompute(), CONSTRAINTSCHEMADisplayToLogical(), CONSTRAINTSCHEMAGet(), CONSTRAINTSCHEMAIsValid(), CONSTRAINTSCHEMALogicalToDisplay(), CONSTRAINTSCHEMALogicalToOdbc(), CONSTRAINTSCHEMANormalize(), CONSTRAINTSCHEMASQLCompute()
property CONSTRAINTTYPE as %String (MAXLEN = 11, VALUELIST = ",FOREIGN KEY,UNIQUE,PRIMARY KEY,CHECK") [ SqlFieldName = CONSTRAINT_TYPE , Required ];
CONSTRAINT_TYPE Returns one of the following values:
- FOREIGN KEY - The constraint being described is a foreign key constraint.
- UNIQUE - The constraint being described is a unique constraint.
- PRIMARY KEY - The constraint being described is a primary key constraint.
- CHECK - The constraint being described is a check constraint.
Property methods: CONSTRAINTTYPEDisplayToLogical(), CONSTRAINTTYPEGet(), CONSTRAINTTYPEIsValid(), CONSTRAINTTYPELogicalToDisplay(), CONSTRAINTTYPELogicalToOdbc(), CONSTRAINTTYPENormalize(), CONSTRAINTTYPESet()
property INITIALLYDEFERRED as %String (MAXLEN = 3, VALUELIST = ",YES,NO") [ Calculated , SqlFieldName = INITIALLY_DEFERRED , Required ];
If the constraint is initially deferred, INITIALLY_DEFERRED returns YES, otherwise NO. InterSystems IRIS only supports non-deferrable constraints.
Property methods: INITIALLYDEFERREDCompute(), INITIALLYDEFERREDDisplayToLogical(), INITIALLYDEFERREDGet(), INITIALLYDEFERREDIsValid(), INITIALLYDEFERREDLogicalToDisplay(), INITIALLYDEFERREDLogicalToOdbc(), INITIALLYDEFERREDNormalize(), INITIALLYDEFERREDSQLCompute()
property ISDEFERRABLE as %String (MAXLEN = 3, VALUELIST = ",YES,NO") [ Calculated , SqlFieldName = IS_DEFERRABLE , Required ];
If the constraint is deferrable, IS_DEFERRABLE returns YES, otherwise NO. InterSystems IRIS only supports non-deferrable constraints.
Property methods: ISDEFERRABLECompute(), ISDEFERRABLEDisplayToLogical(), ISDEFERRABLEGet(), ISDEFERRABLEIsValid(), ISDEFERRABLELogicalToDisplay(), ISDEFERRABLELogicalToOdbc(), ISDEFERRABLENormalize(), ISDEFERRABLESQLCompute()
property TABLECATALOG as %String (MAXLEN = 128) [ Calculated , SqlFieldName = TABLE_CATALOG ];
Table qualifier - always NULL in InterSystems IRIS.
Property methods: TABLECATALOGCompute(), TABLECATALOGDisplayToLogical(), TABLECATALOGGet(), TABLECATALOGIsValid(), TABLECATALOGLogicalToDisplay(), TABLECATALOGLogicalToOdbc(), TABLECATALOGNormalize(), TABLECATALOGSQLCompute()
property TABLENAME as %String (COLLATION = "Upper", MAXLEN = 128) [ SqlFieldName = TABLE_NAME , Required ];
Name of the table.
Property methods: TABLENAMEDisplayToLogical(), TABLENAMEGet(), TABLENAMEIsValid(), TABLENAMELogicalToDisplay(), TABLENAMELogicalToOdbc(), TABLENAMENormalize(), TABLENAMESet()
property TABLESCHEMA as %String (COLLATION = "Upper", MAXLEN = 128) [ SqlFieldName = TABLE_SCHEMA , Required ];
Name of schema that contains the table.
Property methods: TABLESCHEMADisplayToLogical(), TABLESCHEMAGet(), TABLESCHEMAIsValid(), TABLESCHEMALogicalToDisplay(), TABLESCHEMALogicalToOdbc(), TABLESCHEMANormalize(), TABLESCHEMASet()
