Oracle存储过程（分页、模糊查找、排序、按字段区间查找）etc.以及JAVA代码

-- 先创建包

CREATE OR REPLACE PACKAGE mypackage AS TYPE mycursor IS REF CURSOR;

END;

 

--创建分页存储过程

CREATE OR REPLACE PROCEDURE splitpage

(

v_tableName IN VARCHAR2,

v_pageSize IN NUMBER,

v_pageNow IN NUMBER,

v_myTotalRows OUT NUMBER,

v_myTotalPageCount OUT NUMBER,

v_cursor OUT mypackage.mycursor

)

IS

v_sql VARCHAR2(1000);

v_begin NUMBER:=(v_pageNow-1)*v_pageSize+1;

v_end   NUMBER:=v_pageNow*v_pageSize;



BEGIN

  v_sql:='select * from(

                 select rownum rn,a1.* from(

                   select * from ' ||v_tableName|| 

                 ') a1 where rownum<='||v_end||

          ') where rn>='||v_begin||'';

  OPEN v_cursor FOR v_sql;

  v_sql:='select count(*) from ' ||v_tableName||'';

  EXECUTE IMMEDIATE v_sql INTO v_myTotalRows;

  IF MOD(v_myTotalRows,v_pageSize)=0 THEN

    v_myTotalPageCount:=v_myTotalRows/v_pageSize;

  ELSE

    v_myTotalPageCount:=v_myTotalRows/v_pageSize+1;

  END IF;

END;

　　

public YOURClass getSplitPage(int targetPage, int eachpagenum){

		Connection conn = DBConnection.getConn();//获取Oraccle 的Connection

                

                //参数位置要与存储过程对应，其余用法跟pstmt类似

		String sql = "{call splitpage(?,?,?,?,?,?)}";

		try{

			cs = conn.prepareCall(sql);

			cs.setString(1,"tablename"); // the name of db's table

			cs.setInt(2,eachpagenum); // Each page record numbers 

			cs.setInt(3,targetPage); // Target page number



			// register the output

			cs.registerOutParameter(4,OracleTypes.NUMBER);

			cs.registerOutParameter(5,OracleTypes.NUMBER);

			cs.registerOutParameter(6,OracleTypes.CURSOR);



			cs.execute();

			// get the value from CallableStatement

			totalRowsCount = cs.getInt(4); // 获取总记录数

			totalPagesCount = cs.getInt(5);// 获取总页数

			ResultSet rs = (ResultSet) cs.getObject(6);



			while(rs.next()){

				// 从rs中读取数据

			}

			return YOURClass;

		}catch (SQLException e){

			e.printStackTrace();

		}

		return null;

	}

　　下面就不给出JAVA代码了，因为都是类似的。用法跟pstmt一样，只是多了注册输出变量。

 

--带模糊查询的分页

CREATE OR REPLACE PROCEDURE splitpagefuzzy

(

v_colName IN VARCHAR2,

v_keyword IN VARCHAR2,

v_pageSize IN NUMBER,

v_pageNow IN NUMBER,

v_myTotalRows OUT NUMBER,

v_myTotalPageCount OUT NUMBER,

v_cursor OUT mypackage.mycursor

)

IS

v_sql VARCHAR2(1000);

v_begin NUMBER:=(v_pageNow-1)*v_pageSize+1;

v_end   NUMBER:=v_pageNow*v_pageSize;



BEGIN

  v_sql:='select * from(

                 select rownum rn,a1.* from(

                   select * from ' ||v_tableName||' where '||v_colName||' like ''%'|| v_keyword ||'%'' '||

                 ') a1 where rownum<='||v_end||

          ') where rn>='||v_begin||'';

  OPEN v_cursor FOR v_sql;

  v_sql:='select count(*) from ' ||v_tableName||'';

  EXECUTE IMMEDIATE v_sql INTO v_myTotalRows;

  IF MOD(v_myTotalRows,v_pageSize)=0 THEN

    v_myTotalPageCount:=v_myTotalRows/v_pageSize;

  ELSE

  END IF;

END;

　　

--带模糊查询带排序的分页

CREATE OR REPLACE PROCEDURE splitpagefuzzyorder

BEGIN

  v_sql:='select * from(

                 select rownum rn,a1.* from(

    v_myTotalPageCount:=v_myTotalRows/v_pageSize;

  ELSE

    v_myTotalPageCount:=v_myTotalRows/v_pageSize+1;

  END IF;

END;

　　

--带模糊查询带排序带时间段的分页

CREATE OR REPLACE PROCEDURE splitpagefuzzyorderdate

(

v_colName IN VARCHAR2,

v_keyword IN VARCHAR2,

v_colOrder IN VARCHAR2,

IS

v_begin NUMBER:=(v_pageNow-1)*v_pageSize+1;

v_end   NUMBER:=v_pageNow*v_pageSize;



BEGIN

  v_sql:='select * from(

                 select rownum rn,a1.* from(

                   select * from ' ||v_tableName||' where '||v_colName||' like ''%'|| v_keyword ||'%'' '||

                   ' and ' v_colDate||' between ' v_dateBegin ||' and '||v_dateEnd ||

                   ' order by ' ||v_colOrder||' '||

                 ') a1 where rownum<='||v_end||

          ') where rn>='||v_begin||'';

  OPEN v_cursor FOR v_sql;

  v_sql:='select count(*) from ' ||v_tableName||'';

  EXECUTE IMMEDIATE v_sql INTO v_myTotalRows;

  IF MOD(v_myTotalRows,v_pageSize)=0 THEN

    v_myTotalPageCount:=v_myTotalRows/v_pageSize;

  ELSE

    v_myTotalPageCount:=v_myTotalRows/v_pageSize+1;

  END IF;

END;

　　这几个下来想必大家也都清楚该怎么做了。如果需要添加什么条件，只需要在最内层字句中添加相应语句。
