批量修改表名字

using SqlSugar;

namespace 批量修改数据库表名
{
    internal class Program
    {
        static void Main(string[] args)
        {
            SqlSugarClient sqlSugarClient = new SqlSugarClient(new ConnectionConfig()
            {
                ConnectionString = "Data Source=(localdb)\\MSSQLLocalDB;Initial Catalog=testchangetablename;Integrated Security=True;Connect Timeout=30;Encrypt=False;Trust Server Certificate=False;Application Intent=ReadWrite;Multi Subnet Failover=False",
                DbType = DbType.SqlServer,
                IsAutoCloseConnection = true
            });
            var tables = sqlSugarClient.DbMaintenance.GetTableInfoList(false);//true 走缓存 false不走缓存
            foreach (DbTableInfo item in tables)
            {
                if (item.Name.StartsWith("test01_"))
                {
                    var newName = item.Name.Replace("test01_", "test02_");
                    sqlSugarClient.DbMaintenance.RenameTable(item.Name, newName);
                }
            }
