sadGDd asd : 342,45 sdSf
sdlkjk k k30 234.34  ss
sdfkHHkdsf 3422

我需要选择子串

substr(col1)

234.34
3422

Answer 1

你可以使用

Answer 2

Aleks得到了很好的答案，但他的正则表达式匹配表达式如123.456,789.1011,1516.1718

我认为最好使用：

 public class RequestConsumer :
    IConsumer<StartFlowCommand>,
    IConsumer<List<StartAndNextCommand>>
{
    readonly IWorkFlowHandler _flowHandler;
    public RequestConsumer(IContainer container)
    {
        _flowHandler = container.Resolve<IWorkFlowHandler>();
    }

    public async Task Consume(ConsumeContext<StartAndNextCommand> context)
    {
        var result =await  _flowHandler.WorkFlowStartNext(context.Message);
        await context.RespondAsync(result);
    }


    public async Task Consume(ConsumeContext<List<StartAndNextCommand>> context)
    {
        var result = await Task.Run(() => _flowHandler.WorkFlowStartNextBatch(context.Message));
        await context.RespondAsync(result);
    }

SQLITE选择带有数字的子字符串
