[英]cx_Oracle and output variables
I'm trying to do this again an Oracle 10 database: 我正在尝试再次执行Oracle 10数据库:
cursor = connection.cursor()
lOutput = cursor.var(cx_Oracle.STRING)
cursor.execute("""
BEGIN
%(out)s := 'N';
END;""",
{'out' : lOutput})
print lOutput.value
but I'm getting 但我得到了
DatabaseError: ORA-01036: illegal variable name/number
Is it possible to define PL/SQL blocks in cx_Oracle this way? 是否有可能以这种方式在cx_Oracle中定义PL / SQL块?
Yes, you can do anonymous PL/SQL blocks. 是的,你可以做匿名的PL / SQL块。 Your bind variable for the output parameter is not in the correct format.
输出参数的绑定变量格式不正确。 It should be
:out
instead of %(out)s
它应该是
:out
而不是%(out)s
cursor = connection.cursor()
lOutput = cursor.var(cx_Oracle.STRING)
cursor.execute("""
BEGIN
:out := 'N';
END;""",
{'out' : lOutput})
print lOutput
Which produces the output: 产生输出:
<cx_Oracle.STRING with value 'N'>
