EssUpdateFileASOEx

Sends an update specification to the active aggregate storage database from a file, capturing any data load errors in ppMbrError.

Syntax

ESS_FUNC_M EssUpdateFileASOEx (hDestCtx, hSrcCtx, AppName, DbName, FileName, Store, Unlock, ulBufferId, ppMbrError);
ParameterData TypeDescription

hDestCtx

ESS_HCTX_T

API context handle of target database on the server.

hSrcCtx

ESS_HCTX_T

API context handle for update file location. The update file can reside on the client or on the same server as the target database.

AppName

ESS_STR_T

Application name for update file location.

DbName

ESS_STR_T

Database name for update file location

FileName

ESS_STR_T

Name of update specification file.

Store

ESS_BOOL_T

Controls storage of data. If TRUE, data is stored in the server; if FALSE, no data is stored.

Unlock

ESS_BOOL_T

Not supported for aggregate storage databases. You must always pass ESS_FALSE for this parameter.

ulBufferId

ESS_ULONG_T

ID number for the data load buffer.

ppMbrError

ESS_PPMBRERR_T

Pointer to linked list of errors contained in ESS_MBRERR_T. Possible errors are:

  • AD_MSGDL_ERRORLOAD—Unable to do dataload at Item/Record [number].

  • ESS_MBRERR_BADDATA—Invalid member [membername] in data column.

  • ESS_MBRERR_DBACCESS—You have insufficient access privilege to perform a lock on this database.

  • ESS_MBRERR_DUPLICATE—Duplicate members from the same dimension on data record, [number] records completed.

  • ESS_MBRERR_UNKNOWN—Unknown member [membername] in dataload, [number] records returned.

Notes

If the Store flag is set to FALSE, the database merely performs a syntax check of the update specification.

Return Value

Returns zero if successful; otherwise, returns an error code and the records that caused the error.

Access

This function requires the caller to have write privilege (ESS_PRIV_WRITE) to the active database.
