存储过程(Stored Procedure)是在大型数据库系统中,一组为了完成特定功能的SQL语句集,存储过程在数据库中,经过第一次编译后再次调用不需要二次编译。用户通过指定的存储过程名称应传给参数来调用完成。 存储过程就是解决特定问题,有先后顺序的一组SQL语句集合。 在Oracle数据库中存储过程是Procedure。 二、存储过程优缺...
1:getInt(int parameterIndex)、getInt(String parameterName)、还有getString、getBigDecimal、getString、getDate、getURL等等都类似和PreparedStatement与Statement中的用法类似。 2:registerOutParameter(int parameterIndex, int sqlType):按顺序位置parameterIndex将OUT参数注册为JDBC类型sqlType。 3:wasNull():查询最后一...
Calling a stored procedure from your Connector/NET application is similar to techniques you have seen earlier in this tutorial. A MySqlCommand object is created, but rather than taking an SQL query as a parameter, it takes the name of the stored procedure to call. Set the MySqlCommand object...
Create the SQL query using the DB Tools Create Parameterized Query VI. To call a stored procedure, set the Stored Procedure? node to True on the DB Tools Create Parameterized Query VI. The SQL query will be in the form {call storedprocedure (?,?)}. The question marks correspond to the...
A stored procedure, by definition, is a segment of declarative SQL code which is stored in the database catalog and can be invoked later by a program, a trigger or even a stored procedure. A stored procedure, which calls itself, is recursive stored procedure. Almost RDMBS supports recursive...
Chapter One: Stored Procedure as Database Programming Model Although stored procedures have been around for more than a decade now, there still is a recurrent, almost ideological, debate on this programming model. Although it takes position in favor of stored procedures, the intent of this book ...
Connector/J exposes stored procedure functionality through JDBC'sCallableStatementinterface. The following example shows a stored procedure that returns the value ofinOutParamincremented by 1, and the string passed in usinginputParamas aResultSet: ...
For partitioned containers, when you run a stored procedure, you must provide a partition key value in the request options. Stored procedures are always scoped to a partition key. Items that have a different partition key value aren't visible to the stored procedure. This principle also applies...
