Sends an update specification to the active database from a file. The update data can either be stored in the database, or just verified and any errors returned. Also, any data blocks locked for update can be unlocked by this call.
Syntax
EsbUpdateFile (hDestCtx, hSrcCtx, AppName, DbName, FileName, isStore, isUnlock) ByVal hDestCtx As Long ByVal hSrcCtx As Long ByVal AppName As String ByVal DbName As String ByVal FileName As String ByVal isStore As Integer ByVal isUnlock As Integer
Parameter | Description |
---|---|
hDestCtx | VB API context handle of a target database on the server. |
hSrcCtx | VB API context handle for the update file location. The report file can reside on the client or on the same server as the target database. |
AppName | Application name for the update file location. |
DbName | Database name for the update file location. |
FileName | Name of the update specification file. |
isStore | Controls storage of data. If TRUE, data is stored in the server; if FALSE, no data is stored. |
isUnlock | Controls unlocking of data blocks. If TRUE, all relevant blocks which are locked will be unlocked (after data is stored, if necessary). If FALSE, no blocks are unlocked. |
Notes
If this function causes data to be stored (Store flag is TRUE), the relevant data blocks must previously have been locked for update (e.g. by calling EsbReport() with the Lock flag set to TRUE).
If both the Store and Unlock flags are set to FALSE, the database merely performs a syntax check of the update specification.
Return Value
None.
Access
This function requires the caller to have write privilege (ESB_PRIV_WRITE) to the active database.
Example
Declare Function EsbUpdateFile Lib "ESBAPIN" (ByVal hDestCtx As Long, ByVal hSrcCtx As Long, ByVal AppName As String, ByVal DbName As String, ByVal FileName As String, ByVal Store As Integer, ByVal Unlock As Integer) As Long Sub ESB_UpdateFile () Dim sts As Long Dim AppName As String Dim DbName As String Dim FileName As String Dim Store As Integer Dim pUnlock As Integer Dim hSrcCtx As Long AppName = "Sample" DbName = "Basic" '*************************************** ' Update file is an object at the server * '*************************************** hSrcCtx = hCtx FileName = "update" Store = ESB_YES pUnlock = ESB_NO '************ ' Update File '************ sts = EsbUpdateFile (hCtx, hSrcCtx, AppName, DbName, FileName, Store, pUnlock) End Sub
