[Source] MySQL Learning Notes' MySQL Parameter

When operating a database in .net.

Everyone likes to use sqlparameters.

Parameters are precompiled to speed up and inject proof.

Use sqlparameter when using mssql.

Use mysqlparameters when using mysql.

When using mysql for the first time, I often make a mistake

For example, when using mssql, a query is written like this


When using mysql, the query statement must be like this

SQL Server became @

mysql became?

Oracle species become:
Similarly, at what parameter

mssql is like this


MySQL is like this

There is also when specifying the parameter type
MySqlDbType does not have nchar...

Of course, Access is also different, it is nothing more than the difference in symbols, and the rest is not much different.

The above is my summary. Personal experience, share with everyone.
