【问题描述】：

使用机器人框架连接 Sybase DB 然后删除行，更新表中的行。

在机器人框架中执行以下查询时，它工作正常。

Sybase 数据库连接 - 一次性删除和更新

connect To Database Using Custom Params    pyodbc    "Driver={Adaptive Server Enterprise}; server=<myserver>; port=<myport>;db=<mydb>;uid=<myuser>; pwd=<mypasswd>;"
# Run Select Query
@{selectQuery}    Query    select * from TABLE where FIELD1 = '1000'
Log Many    @{selectQuery}
Log    "Selected Query Executed"
# Run Delete Query
@{DeleteQuery}    Execute Sql String    set chained off ; Delete from TABLE where FIELD1 = '1000' AND FIELD2 = 'VALUE2' AND FIELD3 = 'VALUE3'
Log Many    @{DeleteQuery}
Log    "Delete Query Executed"
#Run Update Query
@{updateQuery}    Execute Sql String    set chained off ; UPDATE TABLE SET FIELD2 = 'VALUE2' where FIELD1 = '1001'
Log Many    @{updateQuery}
Log    "Update Query Executed"
Disconnect From Database

而当使用 for 循环时：

Sybase 数据库连接 - 使用 for 循环删除多遍

connect To Database Using Custom Params    pyodbc    "Driver={Adaptive Server Enterprise}; server=<myserver>; port=<myport>;db=<mydb>;uid=<myuser>; pwd=<mypasswd>;"
#Run DELETE Query
:FOR    ${num}    IN RANGE    100
\    Execute Sql String    set chained off ; Delete from TABLE where FIELD1 = ${num} and FIELD2= "${VALUE2[${num}]}" and FIELD3 = "${VALUE3[${num}]}"
\    sleep    1

失败并出现以下错误：

[Sybase][ODBC Driver][Adaptive Server Enterprise]SET CHAINED command not allowed within multi-statement transaction.\n (226) (SQLExecDirectW);

[Sybase][ODBC Driver][Adaptive Server Enterprise]Stored procedure 'abc_sp' may be run only in unchained transaction mode. The 'SET CHAINED OFF' command will cause the current session to use unchained transaction mode.\n (7713)")

【解决方案1】：

使用了提交

下面的 for 循环运行良好。

connect To Database Using Custom Params    pyodbc    "Driver={Adaptive Server Enterprise}; server=<myserver>; port=<myport>;db=<mydb>;uid=<myuser>; pwd=<mypasswd>;"

#Run DELETE Query
:FOR    ${num}    IN RANGE    100
\    Execute Sql String    commit
\    Execute Sql String    set chained off ; Delete from TABLE where FIELD1 = ${num} and FIELD2= "${VALUE2[${num}]}" and FIELD3 = "${VALUE3[${num}]}"
\    Execute Sql String    commit
