Many friends in Java Development, when using Oracle database, often encounter a ORA-01000: maximum open cursors exceeded. Error.In fact, the cause of this error is mainly caused by code problems.Ora-01000: maximum open cursors exceeded.Indicates that the maximum number of opened cursors has been reached for a process.The main cause of this error is that the Java code is executing Conn. createstatement () an

In MySQL, specific exceptions require specific processing. These exceptions can be linked to errors, as well as general process control in subroutines. Defining an exception is a prior definition of the problem encountered during the execution of a program, which defines how it should be handled when a problem is encountered, and that the stored procedure or function can continue to execute when an error is encountered or a warning. 1 Exception definition 1.1 Grammar DECLARE condition_name co

The standard SQLException provides a standardized information segment (SQLState) and a vendor-specific information segment (ErrorCode). As with most databases and their JDBC driver implementations, Oracle databases and JDBC drivers provide more detailed information about the problem through vendor-specific error codes than through SQLException vendor-Independent SQLState The component provides much more inf

Stored Procedure 5-handling of conditions and exceptions and handling of Stored Procedure exceptions Exception Handling can be used for general process control in subprograms. If you want to handle errors during SQL Execution, you can use exception handling. For example, for errors or warnings that may occur in Stored Procedures, triggers, or internal functions, capture related exceptions or exceptions, and then handle them accordingly. I.

Exception Handling can be used for general process control in subprograms. If you want to handle errors during SQL Execution, you can use exception handling. For example, for errors or warnings that may occur in Stored Procedures, triggers, or internal functions, capture related exceptions or exceptions, and then handle them accordingly. I. Conditions and handling procedures 1. Declare Conditions Syntax: Declare condition name condition for condition Value The condition values are as follows:

Introduction: DB2Conditional processors play an irreplaceable role in stored procedures. In DB2,SQLThe stored procedure can use the DB2 Condition processor (Condition Handler) to processSQL Error(SQLERROR), SQL warning (SQLWARNING), no data (NOT FOUND) three common conditions and your own defined trigger conditions, you can use include EXIT, CONTINUE) three condition processors, including UNDO and UNDO. The following describes the detailed analysis of SQL errors processed by the DB2 conditional
