here is another short one, without the cost of fetching MetaData
…
def sql = Sql.newInstance(URL,USER,PWD, DRIVER)
def tablename=”any_table”;
table=sql.rows(“select * from “+tablename)
xml = new groovy.xml.MarkupBuilder()
xml.”${tablename}”(){
for (row in table){
Row(){
for (field in row){
“${field.key}”(field.value)

I wanted to do something similar so I altered what you had and made the following: def db = Sql.newInstance(databaseUrl, databaseUsername, databasePassword, databaseDriver) def file = new File("output.xml") def tables = ["tableA", "tableB"] def xml = new MarkupBuilder(file.newWriter()) xml.data { tables.each { table -> xml.table(name:"${table}") { db.eachRow("select * from ${table}".toString()) { row -> def data = [:] def metaData = row.getMetaData() for (i in 0..<metaData.columnCount) { def name = metaData.getColumnLabel(i+1) def value = row[i] data."${name}" = value } xml.row(data) } } } } Pretty much the same thing as yours except I wanted to dump data for multiple tables and I merged the metadata code with iterating the rows. pretty useful way to dump data.

def data = [:]
def metaData = row.getMetaData()

def name = metaData.getColumnLabel(i+1)
def value = row[i]
data.”${name}” = value
}
xml.row(data)
}
}
}
}

Pretty much the same thing as yours except I wanted to dump data for multiple tables and I merged the metadata code with iterating the rows.

I first had some issues in that the exported XML contained the schema's from which I was migrating data, though I ultimately was able to get around that, and then I found my exported xml was not nearly as pretty (I'm picky). Writing the Groovy script probably took less time than learning more about DbUnit to fix my issues. Groovy is a no-brainer language to pick up for a Java developer, and it rocks as a quick, get-it-done, scripting language for tasks such as this.

I've used this in the past to export a prod database to dev to reproduce an issue related to bad data. You can also use DbUnit’s “export” feature to export a database’s tables to XML format.
