JetCreateTableColumnIndex Function

Windows

Last modified: January 09, 2012

Applies to: Windows | Windows Server

The JetCreateTableColumnIndex function creates a table in an ESE database with an initial set of indexes and an initial set of columns from an array of JET_TABLECREATE structures. The name JetCreateTableColumnIndex comes from the order of creation of the objects. It first creates a table, columns, and then finally indexes.

JET_ERR JET_API JetCreateTableColumnIndex(
  __in          JET_SESID sesid,
  __in          JET_DBID dbid,
  __in_out      JET_TABLECREATE* ptablecreate
);

Parameters

sesid

The database session context to use for the API call.

dbid

The database identifier to use for the API call.

ptablecreate

A pointer to a JET_TABLECREATE structure which defines the table to be created. See JET_TABLECREATE for more details.

Return Value

This function returns the JET_ERR datatype with one of the following return codes. For more information about the possible ESE errors, see Extensible Storage Engine Errors and Error Handling Parameters.

Return code

Description

JET_errSuccess

The operation completed successfully.

JET_errCallbackNotResolved

The callback function could not be resolved. The DLL might not have been found, or the function in the DLL might not have been found. With sufficient logging enabled, the event log will provide more details.

JET_errCannotIndex

An attempt was made to index over an escrow-update or SLV column (note that SLV columns are deprecated).

JET_errCannotNestDDL

If ptablecreate->grbit specifies JET_bitTableCreateTemplateTable, but ptablecreate->szTemplateTableName is set to NULL.

JET_errColumnDuplicate

A column already exists.

JET_errColumnNotFound

An attempt was made to index over a non-existent column. Attempting to conditionally index over a non-existent column can also produce this error.

JET_errColumnRedundant

An attempt was made to add a redundant column. There should be no more than one autoincrement column, and no more than one version column per table.

JET_errDensityInvalid

This error will be returned if the ulDensity member of the JET_INDEXCREATE structure is set to a number less than 20 or more than 100.

JET_errDDLNotInheritable

Signifies that the table named in the szTemplateTableName member of the JET_TABLECREATE structure was not marked as a template table (that is, that table did not have JET_bitTableCreateTemplateTable set).

JET_errIndexDuplicate

An attempt to define two identical indexes was made.

JET_errIndexHasPrimary

An attempt was made to specify more than one primary index for a table. A table must have exactly one primary index. If no primary index is specified, the database engine will transparently create one.

JET_errIndexInvalidDef

An invalid index definition was specified. Some of the possible reasons for receiving this error are:

  • A primary index is conditional (that is, the grbit member of the JET_INDEXCREATE structure has JET_bitIndexPrimary set, and cConditionalColumn member of the JET_INDEXCREATE structure is greater than zero).

  • Windows Server 2003 and later. Attempting to create a tuple index with tuple limits, but without passing the ptuplelimits member in the JET_INDEXCREATE structure (that is, the grbit member of the JET_INDEXCREATE structure has JET_bitIndexTupleLimits set, but the ptuplelimits pointer is NULL).

  • Passing in an invalid key definition in the szKey member of the JET_INDEXCREATE structure. See JET_INDEXCREATE for a discussion of valid definitions.

  • Setting the cbVarSegMac member in JET_INDEXCREATE to be greater than JET_cbPrimaryKeyMost (for a primary index) or greater than JET_cbSecondaryKeyMost (for a secondary index).

  • Passing an invalid combination for a user-defined Unicode index (one which has the JET_bitIndexUnicode bit set in the grbit member of JET_INDEXCREATE). Some common causes include the pidxunicode member of the JET_INDEXCREATE structure is NULL, or the LCID specified in the pidxunicode structure is invalid.

  • Specifying a multi-valued column for a primary index.

  • Trying to index too many conditional columns. The cConditionalColumn member of the JET_INDEXCREATE structure must not be greater than JET_ccolKeyMost.

JET_errIndexTuplesInvalidLimits

Windows XP and later. A JET_TUPLELIMITS structure was specified, and its limits are not supported. See the remarks section of the JET_TUPLELIMITS structure.

JET_errIndexTuplesNonUniqueOnly

Windows XP and later. A tuple index cannot be unique (that is, the grbit member of the JET_INDEXCREATE structure must not have both JET_bitIndexPrimary and JET_bitIndexUnique set).

JET_errIndexTuplesOneColumnOnly

Windows XP and later. A tuple index can only be over a single column (that is, if the grbit member of the JET_INDEXCREATE structure has JET_bitIndexTuples set, and the szKey member of the JET_INDEXCREATE structure specifies more than one column).

JET_errIndexTuplesSecondaryIndexOnly

Windows XP and later. A tuple index cannot be a primary index (that is, the grbit member of the JET_INDEXCREATE structure must not have both JET_bitIndexPrimary and JET_bitIndexTuples set).

JET_errIndexTuplesTextColumnsOnly

Windows XP and later. A tuple index can only be on a text or Unicode column. An attempt to index other columns (such as binary columns) will result in JET_errIndexTuplesTextColumnsOnly.

JET_errIndexTuplesVarSegMacNotAllowed

Windows XP and later. A tuple index does not allow the cbVarSegMac member of the JET_INDEXCREATE structure to be set.

JET_errInTransaction

An attempt was made to create an index without version information while in a transaction.

JET_errInvalidCodePage

The cp member of the JET_COLUMNCREATE structure was not set to a valid code page. The only valid values for text columns are English (1252) and Unicode (1200). A value of 0 means the default will be used (English, 1252).

JET_errInvalidColumnType

The coltyp member of the JET_COLUMNCREATE structure was not set to a valid column type.

JET_errInvalidCreateIndex

Some of the reasons this error may occur:

JET_errInvalidgrbit

An invalid combination of grbit members was specified in JET_TABLECREATE or JET_TABLECREATE2.

The index definition is invalid because the grbit member contains inconsistent values. Some possible reasons are:

  • A primary index had an ignore bit specified (that is, JET_bitIndexPrimary was passed with JET_bitIndexIgnoreNull, JET_bitIndexIgnoreAnyNull, or JET_bitIndexIgnoreFirstNull).

  • An empty index does not ignore any NULL members (that is, the grbit member of the JET_INDEXCREATE structure has JET_bitIndexEmpty set, but does not have JET_bitIndexIgnoreAnyNull set).

  • Passing in a JET_CONDITIONALCOLUMN structure with an invalid grbit member.

JET_errInvalidLanguageId

An invalid Locale ID (LCID) was passed in (either through the lcid member of the JET_UNICODEINDEX structure which is pointed to by the pidxunicode member in the JET_INDEXCREATE structure, or through the lcid field of the JET_INDEXCREATE structure).

JET_errInvalidParameter

An invalid parameter was given. Some possible reasons are:

  • The rgcolumncreate member of the JET_TABLECREATE2 structure is NULL.

  • The cbStruct member of one of the JET_COLUMNCREATE structures given in the rgcolumncreate member of the JET_TABLECREATE2 structure was not set to sizeof( JET_COLUMNCREATE).

  • The cbKey member of a JET_INDEXCREATE structure is set to zero.

  • The cbStruct member of a JET_INDEXCREATE structure is not set to sizeof( JET_INDEXCREATE).

JET_errRecordTooBig

The record is too big. The sum of the cbMax member of the JET_COLUMNCREATE structure for all fixed columns must not exceed a certain value.

JET_errTableDuplicate

The table already exists.

JET_errTooManyColumns

An attempt was made to add too many columns to the table. A table can have no more than JET_ccolFixedMost fixed columns, no more than JET_ccolVarMost variable-length columns, and no more than JET_ccolTaggedMost tagged columns.

JET_errUnicodeTranslationFail

An error occurred attempting to normalize a Unicode column. This can be caused by running out of system resources.

Remarks

Calling JetCreateTableColumnIndex is identical to calling JetCreateTableColumnIndex2, with each field in the JET_TABLECREATE2 structure containing the value of the corresponding field of JET_TABLECREATE, with the following exceptions:

  • JET_TABLECREATE2.cbStruct set to sizeof( JET_TABLECREATE2)

  • JET_TABLECREATE2.szCallback set to NULL

  • JET_TABLECREATE2.cbtyp set to 0

See JetCreateTableColumnIndex2 for more details.

Like JetOpenTable, when the application is done using the returned tableid, it should usually be closed with JetCloseTable.
