如何逃避s虫 [英] How to escape back ticks

问题描述

MySQL要求对带有阴影的保留字的表进行打勾.我有一个表Role(表角色)，它是一个保留字，但是我已经将查询放在后面的刻度中，因此可以在多行中写出来(这是一个玩具查询，大的查询不能放在一行上).

MySQL requires tables that shadow reserved words to be back ticked. I have a table Role which is a reserved word, but I have already put my query in back ticks so I can write it over multiple lines (this is a toy query, large ones will not fit on one line).

如何摆脱背escape?

How do I escape the back ticks?

这是我的代码:

dbmap := db.InitDb()

var roles []entities.Role
query :=
    ` << Difficult to see with SO's code editor widget, but here is a back tick
SELECT *
FROM `Role` <<< Needs escaping
`  << Difficult to see, but here is a back tick

_, err := dbmap.Select(&roles, query, nil)
if err != nil {
    panic(err)
}

fmt.Println(roles)

推荐答案

您不能在反引号内转义反引号，但是您可以这样做:

You cannot escape backticks inside backticks, but you can do:

dbmap := db.InitDb()

var roles []entities.Role
query := `
SELECT *
FROM ` + "`Role`"

_, err := dbmap.Select(&roles, query, nil)
if err != nil {
    panic(err)
}

fmt.Println(roles)
