Updating a row in sql using jdbc
In this example, we are looking into the JDBC database tutorial to update and fetch records from the selected My SQL Database table We have already inserted the records in the database, Now we want to update certain fields of the database using the update query, If we want to update the records then we can carry out following steps.
When we are dealing with the database connectivity then we need to include the required jar file which is necessary for the database programming.
Then, using methods of the SQLServer Result Set object, it inserts, modifies, and then finally deletes a row of data from the set of data.
Sample Code: query="update mytable set myfield=:1 where somefield=:2" sql Non Select(query,'myfield','somefield')Here's some background ... cpp"; Line: 1152; Context: "Salmon:: NED:: Node Control::initialize Expert()" Uninstalling log (01/21/2011 ) ... Since I manage to extract data using "JBDC Query", I'm hoping to use "JDBC Execute" to update the records. The table has 6 fields - Id (int), Body (string), End (date), Location (string), Start (date), Subject (string)I manage to run with node without error (Green tick). Here's the query I use sql Non Select("UPDATE Appointments Set Subject=:1 where id=:2",'Subject','Id') Error Log Installing log (01/21/2011 ) ... Error: property ls.Level set incorrectly (set to 2)Error: Allowed values are Critical, Error, Warning, Info, Debug Error: Using Warning Does that help?
EXTRACT I use the "JDBC Query" to retrieve sample data TRANSFORM I use multiple different nodes to manipulate the data LOAD Update the same table using the PK I'm current stuck at the last leg (LOAD). JDBC Execute BRX Description node:4d38fc59050615bb type:binary name: OCMS v2.8. SQLQuery= query = "UPDATE Appointments Set Subject=:1 where id=:2" sql Non Select(query, Subject, Id) EOX prop:ls.java. We have seen a similar behavior when connecting to SQL Server caused by permission issues.
In addition, your application must specify the data type of each returned value using the Callable Statement.register Out Parameter() method.
The registered data type for a returned value must match the data type of the database column.
