Returns the unique modelVersionId and the version sequence number of a version of an edmModel. The version is identified by the model Id and the version name.

Header:
#include "sdai.h"
Prototype:
EdmiError edmiGetModelVersionId(SdaiModel         modelId,
                                 SdaiString        modelVersionName,
                                 SdaiModelVersion *modelVersionId,
                                 SdaiVersion      *versionId);
Arguments:

modelId

The modelId that uniquely identifies the edmModel in the EDMdatabase.

modelVersionName

The name of the model version to look for.

modelVersionId

Variable that will receive the modelVersionId that uniquely identifies the model version in the EDMdatabase.

versionId

Variable that will receive the model version number. This sequence number counts from one and increases by one for each new version created.

Returns:
A completion code of datatype EdmiError is the returned function value. The completion code has the following values:
Completion code = 0 : Operation successfully performed.
Completion code != 0: Error in operation. Completion code is an EDMinterface error code. Use edmiGetErrorText to get the error text corresponding to the error code.
Example:
EdmiError rstat;
SdaiInteger nWrn, nErr;
SdaiRepository repId;
SdaiModel modelId;
SdaiVersion version1Id, version2Id;
SdaiModelVersion modelVersionId;
SdaiInteger myInteger;
SdaiReal myReal;
SdaiInstance instId;
SdaiAttr attrId;
SdaiPrimitiveType type;

/* Create Model */

modelId = edmiCreateModelBN(repId, "MyModel", "MySchema", 0);
/* Populate Model */
instId = edmiCreateInstanceAndPutAttrsBN(modelId, "MyEntity", 1,
"REAL_ATTR", sdaiREAL, 3.14);  
/* Create version 1 */
rstat = edmiCreateModelVersion("MyRepository", "MyModel",
"V1", &modelVersionId); 
/* Change population */
sdaiPutAttrBN(instId, "REAL_ATTR", sdaiINTEGER, 1);
/* Create version 2 */
rstat = edmiCreateModelVersion("MyRepository", "MyModel",
NULL, &modelVersionId); 
/* Get Id of version 1 */
rstat = edmiGetModelVersionIdBN("MyRepository", "MyModel",
"V1", &modelVersionId, &version1Id); 
/* Type is sdaiREAL */
rstat = edmiVersionGetAttrDatatypeBN(instId, version1Id,
"REAL_ATTR", &type);
/* Value is 3.14 */ 
if (type != sdaiREAL) goto error;

/* Get Id of version 2 */
attrId = sdaiGetAttrDefinitionBN("MySchema", "MyEntity",
"REAL_ATTR");
rstat = edmiGetModelVersionId(modelId, "version2",
&modelVersionId, &version2Id); 
/* Type is now sdaiINTEGER */
rstat = edmiVersionGetAttrDatatype(instId, version2Id,
attrId, &type);
/* Value is 1 */
if (type != sdaiINTEGER) goto error;
rstat = edmiVersionGetAttr(instId, version2Id, attrId,
type, &myInteger);
/* Roll back to version 1 */
rstat = edmiRollbackModel(modelId, version1Id,

/* Delete version 2 */
