Changing Target Column Mapping
Changing target column mappings includes:
Opening a CONNX Data Dictionary (CDD).
Changing which target column a source column is mapped to.
Change the target column mappings if you wish to change which target column a source column is mapped to.
After you change the column mappings you will be able to deploy the replication (which will start replicating data from source database to target database).
When InstantdbSync creates a Target Table, it assigns column source and attributes based on the associated Source Table. The Map Columns window allows you to change which target column a source column is mapped to.
Note:
The Source and Target columns must have compatible data types, lengths, precisions and scales.
You cannot use InstantdbSync to delete a row from the Source table.
To change a mapping:
1. Open the InstantdbSync CDD.
2. Select a Target Table to modify. Click Map Columns. The Map Columns window for an existing target table appears.
3. Under Populate columns, click Target Columns.
4. Click the Target Column box for the replication you wish to change. A drop down arrow appears. Click on the arrow and a list of available source column names appears.
5. Select the target column name to map the corresponding target column to.
6. The selected Source Column will map to the corresponding Target Column.
7. Click Done when you are done setting mappings
Note:
The ISN field is always shown in the column map because replication requires a unique key present to work and if there are no other unique keys on the table, the ISN can then be used. The ISN is shown even if the table was built with a Create Table statement that did not specify an ISN.
