Syntax

PRESULT PvAddTable(

WORD dictHandle,

TABLEINFO* tableProps,

COLUMNMAP* columnList,

WORD columnCount,

INDEXMAP* indexList,

WORD indexCount);

Arguments

In	dictHandle	Handle of an open dictionary returned by PvOpenDatabase().
In	tableProps	Structure containing table information.
In	columnList	Array of columns defined in the table.
In	columnCount	Number of columns in columnList.
In	indexList	Array of index definitions.
In	indexCount	Number of indexes in the following indexList array.

Return Values

PCM_Success	The operation was successful.
PCM_errFailed	The operation was not successful.
PCM_errInvalidDictionaryHandle	The specified dictionary handle does not exist.
PCM_errTableNotFound	The specified table was not found.
PCM_errMemoryAllocation	An error occurred during memory allocation.
PCM_errInvalidColumnName	The specified column name is invalid.
PCM_errInvalidDataType	The specified data type is invalid.
PCM_errDuplicateColumnName	The column name already exists in the table.
PCM_errInvalidDataSize	The data size is invalid.
PCM_errInvalidIndexName	Index name is invalid.
PCM_errColumnNotFound	Column specified for a segment cannot be found.

Remarks

You must first open a dictionary successfully using PvOpenDatabase().

This function has to be provided with table information, columns, and indexes. indexCount and indexList are optional parameters because indexes are not required to create a table.

This function will fail if a table with the same name is already present in the specified dictionary.

Table properties must be set up correctly and an array of at least one column must be passed.

You will need to allocate and release COLUMNMAP and INDEXMAP arrays and TABLEINFO structure used to describe table. See also COLUMNMAP Flags.

The offset of a field within its row can be accessed through the PvGetTable() function. The COLUMNMAP structure has been modified in ddfstrct.h to contain this additional information. This new field is ignored when calling the PvAddTable() and PvFreeTable() functions. Refer to ddfstrct.h and ddf.h.
