【SQL骚操作】SqlServer数据库表生成C# Model实体类SQL语句

已知现有表T1

 

 

想快速获取cs类结构

/// <summary>
///  T1    
/// </summary>
public class T1
{
    /// <summary>
    /// 主键    
    /// </summary>
    public int ID { get; set; }

    /// <summary>
    /// 姓名    
    /// </summary>
    public string NameLijhs { get; set; }

}

 

 

通过运行下面的sql即可，先配置表名。

declare @TableName sysname = 'T1'
declare @Result varchar(max) = '
/// <summary>
///  ' +  @TableName +
    
'    
/// </summary>
public class ' + @TableName + '
{'

select @Result = @Result + '
    /// <summary>
    /// ' +  CONVERT(NVARCHAR(500), ISNULL(ColName, '无')) +
    
'    
    /// </summary>
    public ' + ColumnType + NullableSign + ' ' + ColumnName + ' { get; set; }
'
from
(
    SELECT
        replace(col.name, ' ', '_') ColumnName,
        column_id ColumnId,
        prop.value ColName,
        case typ.name
            when 'bigint' then 'long'
            when 'binary' then 'byte[]'
            when 'bit' then 'bool'
            when 'char' then 'string'
            when 'date' then 'DateTime'
            when 'datetime' then 'DateTime'
            when 'datetime2' then 'DateTime'
            when 'datetimeoffset' then 'DateTimeOffset'
            when 'decimal' then 'decimal'
            when 'float' then 'float'
            when 'image' then 'byte[]'
            when 'int' then 'int'
            when 'money' then 'decimal'
            when 'nchar' then 'char'
            when 'ntext' then 'string'
            when 'numeric' then 'decimal'
            when 'nvarchar' then 'string'
            when 'real' then 'double'
            when 'smalldatetime' then 'DateTime'
            when 'smallint' then 'short'
            when 'smallmoney' then 'decimal'
            when 'text' then 'string'
            when 'time' then 'TimeSpan'
            when 'timestamp' then 'DateTime'
            when 'tinyint' then 'byte'
            when 'uniqueidentifier' then 'Guid'
            when 'varbinary' then 'byte[]'
            when 'varchar' then 'string'
            else 'UNKNOWN_' + typ.name
        end ColumnType,
        case
            when col.is_nullable = 1 and typ.name in ('bigint', 'bit', 'date', 'datetime', 'datetime2', 'datetimeoffset', 'decimal', 'float', 'int', 'money', 'numeric', 'real', 'smalldatetime', 'smallint', 'smallmoney', 'time', 'tinyint', 'uniqueidentifier')
            then '?'
            else ''
        end NullableSign
    from sys.columns col
        join sys.types typ on
            col.system_type_id = typ.system_type_id AND col.user_type_id = typ.user_type_id
            LEFT JOIN sys.extended_properties prop ON col.object_id = prop.major_id AND col.column_id = prop.minor_id
    where object_id = object_id(@TableName)
) t
--order by ColumnId

set @Result = @Result  + '
}'

print @Result

 

效果如下：

 

 

完美，copy到项目里即可。

 

declare @TableName sysname = 'AUTHSYSTEMCHANGE' --表名

            when 'bigint' then 'long'
            when 'binary' then 'byte[]'
            when 'bit' then 'bool'
            when 'char' then 'string'
