Question

如何在Gradle任务中执行SQL？

configurations {
    compile
}
repositories {
    mavenCentral()
}
dependencies {
    compile 'postgresql:postgresql:9.0-801.jdbc4'
}
task sql << {
    driverName = 'org.postgresql.Driver'
    Class.forName(driverName)
    groovy.sql.Sql sql = Sql.newInstance(
        'jdbc:postgresql://localhost:5432/postgres', 
        'username', 
        'password', 
        driverName
    )
    sql.execute 'create table test (id int not null)'
    sql.execute 'insert into test (id) values(1)'
    sql.eachRow 'select * from test' {
        println it
    }
}

我得到了执行sql任务时出现 java.lang.ClassNotFoundException：org.postgresql.Driver 异常。

Answer 1

要定义external dependencies for the build script本身，您必须将其放入构建脚本的类路径中。你可以通过在buildscript闭包中定义它来做到这一点。

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'postgresql:postgresql:9.0-801.jdbc4'
    }
}

如果您不介意依赖其他工具，则可以在项目中使用dbdeploy。还有一个gradle plugin，可以按原样导入SQL脚本。

Answer 3

buildscript {
    dependencies {
        classpath 'com.oracle:ojdbc6:11.2.0.3'
    }
}

task tmp() {
    dependsOn configurations.batch
    doLast {
        ant.sql(classpath: buildscript.configurations.classpath.asPath,
            driver: "oracle.jdbc.OracleDriver",
            url: "${dbConn}", userid: "${dbUser}", password: "${dbPass}",
            "select 1 from dual")
    }
}

可替换地：

ant.sql(classpath: buildscript.configurations.classpath.asPath,
        driver: "oracle.jdbc.OracleDriver",
        url: "${dbConn}", userid: "${dbUser}", password: "${dbPass}") {
    fileset(dir: dir) {
        include(name: "**/*.sql")
    }
}

Answer 4

这是一种方式：

gradle.class.classLoader.addURL(new File('../../../../lib/server/mssql/sqljdbc4.jar').toURI().toURL())
def Sql sql = Sql.newInstance(dbConnectionURL, dbUserName, dbPassword, dbDriverName)
String sqlString = new File(dbSchemaFile as String).text

sql.execute(sqlString)
