Java DatabaseMetaData getMaxProcedureNameLength() method with example.
The getMaxProcedureNameLength() method of the DatabaseMetaData interface is used to find out the maximum number of characters that the underlying database allows in the name of a procedure.
This method returns an integer value, representing the maximum number of characters allowed in a procedure name. If this value is 0 it indicates that there is no limit or, limit is unknown.
To get the DatabaseMetaData object −
Make sure your database is up and running.
Register the driver using the registerDriver() method of the DriverManager class. Pass an object of the driver class corresponding to the underlying database.
Get the connection object using the getConnection() method of the DriverManager class. Pass the URL the database and, user name, password of a user in the database, as String variables.
Get the DatabaseMetaData object with respect to the current connection using the getMetaData() method of the Connection interface.
Finally, get the maximum length of the procedure name, by invoking the getMaxProcedureNameLength() method (of the DatabaseMetaData interface).
Example
Following JDBC example connects to MySQL database, retrieves and prints the maximum length of the procedure name, allowed by it.
import java.sql.Connection; import java.sql.DatabaseMetaData; import java.sql.DriverManager; import java.sql.SQLException; public class DatabaseMetadata_getMaxProcedureNameLength { public static void main(String args[]) throws SQLException { //Registering the Driver DriverManager.registerDriver(new com.mysql.jdbc.Driver()); //Getting the connection String url = "jdbc:mysql://localhost/mydatabase"; Connection con = DriverManager.getConnection(url, "root", "password"); System.out.println("Connection established......"); //Retrieving the meta data object DatabaseMetaData metaData = con.getMetaData(); //Retrieving the maximum number length of the procedure name allowed int maxLength = metaData.getMaxProcedureNameLength(); System.out.println("Maximum length of the procedure name allowed: "+maxLength); } }
Output
Connection established...... Maximum length of the procedure name allowed: 0
