第一个方法是使用 GET DIAGNOSTICS,它的形式如下: GET DIAGNOSTICS variable = item [ , ... ] ; 这条命令允许我们检索系统状态标识符。每个 item 是一个关键字,表示一个将要赋予该特定变量的状态值(该变量应该和要接收的数值类型相同)。 当前可用的状态项有 ROW_COUNT, 最后一个发送给 SQL 引擎的 SQL 命...
GET DIAGNOSTICS捕获运行过程中的状态值 There are several ways to determine the effect of a command. The first method is to use the GET DIAGNOSTICS command, which has the form: GET [ CURRENT ] DIAGNOSTICS variable { = | := } item [ , ... ]; GET DIAGNOSTICS integer_var = ROW_COUNT;...
GET DIAGNOSTICS variable = item [ , ... ]; 1. 其中的item可以是ROW_COUNT和RESULT_OID。ROW_COUNT表示上一条SQL命令处理的数据行的个数。RESULT_OID表示最近的SQL命令插入的最后一个数据行的OID。variable是一个变量。例如: GET DIAGNOSTICS integer_var = ROW_COUNT; ...

对于merge into语法的转换,在ADB for PG中先使用update进行更新,然后使用GET DIAGNOSTICS rowcount := ROW_COUNT;语句获取update更新的行数,如果update更新的行数为0,那么再使用insert语句进行插入。 MERGE INTO test1 t1 USING (SELECT t2.col1 col1, t3.col2 col2, ...
