SQL 查询未从 bash 脚本执行

Question

我目前有以下功能，我知道当我通过 GUI SQL 客户端手动运行时输出的查询有效，但它在 Bash 中不起作用... 我尝试了所有我能想到的方法，并用我能想到的关键字进行了谷歌搜索..

AssignChunksToDocs()
{
TEST="set heading off;
        set trim on;
        DECLARE
        i number;

        BEGIN
                i := 1;


                while i<=$CHUNK_AMOUNT LOOP
                  UPDATE TABLE T SET T.CHUNK_NUM = i
                  WHERE T.CHUNK_NUM IS NULL
                  AND ROWNUM <=$DOCS_PER_CHUNK;
                  i := i+1;
                END LOOP;
        i := i-1;
        -- Deal with the remainder
        UPDATE TABLE T SET T.CHUNK_NUM = i
        WHERE T.CHUNK_NUM IS NULL;

        end;"

        sqlplus -s $CONSTR<<ENDOFSQL
        set heading off;
        set trim on;
        DECLARE
        i number;

        BEGIN
                i := 1;


                while i<=$CHUNK_AMOUNT LOOP
                  UPDATE TABLE T SET T.CHUNK_NUM = i
                  WHERE T.CHUNK_NUM IS NULL
                  AND ROWNUM <=$DOCS_PER_CHUNK;
                  i := i+1;
                END LOOP;
        i := i-1;
        -- Deal with the remainder
        UPDATE TABLE T SET T.CHUNK_NUM = i
        WHERE T.CHUNK_NUM IS NULL;

        end;
ENDOFSQL

ERRORCODE=$?
if [ $ERRORCODE != 0 ]
then
  echo "********************"
  echo "ERROR: The SQL Plus Command Failed. ErrorCode: $ERRORCODE"
else
  echo "********************"
  echo "SQL Plus Successfully Ran. ErrorCode: $ERRORCODE"
fi

}

当我运行它时（在 shebang 中使用 -x），我得到以下片段：

+ AssignChunksToDocs
+ TEST='set heading off;
        set trim on;
        DECLARE
        i number;

        BEGIN
                i := 1;


                while i<=
        64 LOOP
                  UPDATE TABLE T SET T.CHUNK_NUM = i
                  WHERE T.CHUNK_NUM IS NULL
                  AND ROWNUM <=3;
                  i := i+1;
                END LOOP;
        i := i-1;
        -- Deal with the remainder
        UPDATE TABLE T SET T.CHUNK_NUM = i
        WHERE T.CHUNK_NUM IS NULL;

        end;'
+ sqlplus -s dbuser/dbpass@hostname/sidname
+ ERRORCODE=0
+ '[' 0 '!=' 0 ']'
+ echo '********************'
********************
+ echo 'SQL Plus Successfully Ran. ErrorCode: 0'
SQL Plus Successfully Ran. ErrorCode: 0

在终端命令行中手动测试查询，然后手动粘贴 << SQL ... SQL 块也是如此。

请帮忙:)

问题原来是缺少 COMMIT; 语句！将来，如果出现类似没有错误但数据库中没有明显发生的奇怪情况，请让 DBA 查找 table 锁！

它们两次是导致它因缺少 COMMIT 而不起作用的原因；在每个更新语句之后。
