本文主要是介绍oracle 如何把表导出csv，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
CREATE OR REPLACE PROCEDURE SQL_TO_CSV ( P_QUERY IN VARCHAR2, -- PLSQL文 P_DIR IN VARCHAR2, -- 导出的文件放置目录 P_FILENAME IN VARCHAR2 -- CSV名 ) IS L_OUTPUT UTL_FILE.FILE_TYPE; L_THECURSOR INTEGER DEFAULT DBMS_SQL.OPEN_CURSOR; L_COLUMNVALUE VARCHAR2(4000); L_STATUS INTEGER ; L_COLCNT NUMBER := 0; L_SEPARATOR VARCHAR2(1); L_DESCTBL DBMS_SQL.DESC_TAB; P_MAX_LINESIZE NUMBER := 32000; BEGIN --OPEN FILE L_OUTPUT := UTL_FILE.FOPEN(P_DIR, P_FILENAME, ‘W’, P_MAX_LINESIZE); --DEFINE DATE FORMAT EXECUTE IMMEDIATE ‘ ALTER SESSION SET NLS_DATE_FORMAT=’’YYYY-MM-DD HH24:MI:SS’’’; --OPEN CURSOR DBMS_SQL.PARSE( L_THECURSOR, P_QUERY, DBMS_SQL.NATIVE ); DBMS_SQL.DESCRIBE_COLUMNS( L_THECURSOR, L_COLCNT, L_DESCTBL ); --DUMP TABLE COLUMN NAME FOR I IN 1 .. L_COLCNT LOOP UTL_FILE.PUT( L_OUTPUT, L_SEPARATOR || ‘”’ || L_DESCTBL(I).COL_NAME || ‘”’ ); DBMS_SQL.DEFINE_COLUMN( L_THECURSOR, I, L_COLUMNVALUE, 4000 ); L_SEPARATOR := ‘,’; END LOOP; UTL_FILE.NEW_LINE( L_OUTPUT ); --EXECUTE THE QUERY STATEMENT L_STATUS := DBMS_SQL. EXECUTE (L_THECURSOR); --DUMP TABLE COLUMN VALUE WHILE ( DBMS_SQL.FETCH_ROWS(L_THECURSOR) > 0 ) LOOP L_SEPARATOR := ‘’; FOR I IN 1 .. L_COLCNT LOOP DBMS_SQL.COLUMN_VALUE( L_THECURSOR, I, L_COLUMNVALUE ); UTL_FILE.PUT( L_OUTPUT, L_SEPARATOR || ‘”’ || TRIM(BOTH ‘ ‘ FROM REPLACE (L_COLUMNVALUE,’”’,’””’)) || ‘”’); L_SEPARATOR := ‘,’; END LOOP; UTL_FILE.NEW_LINE( L_OUTPUT ); END LOOP; --CLOSE CURSOR DBMS_SQL.CLOSE_CURSOR(L_THECURSOR); --CLOSE FILE UTL_FILE.FCLOSE( L_OUTPUT ); EXCEPTION WHEN OTHERS THEN RAISE; END ; 这篇关于oracle 如何把表导出csv的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
