我知道如何从 bash 执行 MySQL 查询/命令:
I know how one can execute MySQL queries / commands from bash:
mysql -u[user] -p[pass] -e "[mysql commands]"
或
mysql -u[user] -p[pass] `<<`QUERY_INPUT
[mysql commands]
QUERY_INPUT
如何捕获受查询影响的行数?
我试着做:
How can I capture how many rows were affected by the query?
I tried doing:
variable='`mysql -u[user] -p[pass] -e "[mysql commands]"`'
它确实执行了命令,但不返回受影响的行数.
It does execute the command but it does not return the number of affected rows.
Put
SELECT ROW_COUNT();
作为批处理中的最后一条语句并解析输出
as the last statement in your batch and parse the output
