Can't display the style

Question

When I load the feature source and style in the map layer it does not always display.

The feature and style were loaded in mapcontent: (http://tva1.sinaimg.cn/large/007X8olVly1g6s6dbbhqdj30w00i0ta5.jpg )

We need to see the content of some of your features and the whole of the SLD, the other code is irrelevant - though you should probably use a DataStore not an SQL query. — Ian Turton, Sep 08 '19 at 09:33

If anyone has the same confusion that you have loaded the style and featuresource in the map layer,but it not display,maybe you should adjustment the MaxScaleDenominator or MinScaleDenominator in .sld file. It's a amusing question,but it cost my 1 week and 6 reputations.

Can't display the style
