Question

我收到此错误，但无法找出原因。

case when FormFields.fieldtype like '%date%'        
    then 'not' + fieldname + ' is null and ( convert(datetime,' 
         + fieldname +',103)  < ' 
         + coalesce(str(FormFields.MinDate),'1/1/1900') + ')' 
         + ' or ( convert(datetime,' + fieldname +',103) > ' 
         + coalesce(str(FormFields.MaxDate), '1/1/2200') + ')' 
         +
else     
         'not '+ fieldname + ' is null and ( convert(float,'+ fieldname+') <'
         + coalesce(str(FormFields.MinValue),'-99999999') 
         + ' or convert(float,'+ fieldname+') >' 
         + coalesce(str(FormFields.MaxValue),'99999999') +')' 
         +
end

以前的代码没有任何错误：

'not '+ fieldname + ' is null and ( convert(float,'+ fieldname+') <'
     + coalesce(str(FormFields.MinValue),'-99999999') 
     + ' or convert(float,'+ fieldname+') >' 
     + coalesce(str(FormFields.MaxValue),'99999999') +')' 
     +

我只想添加另一个案例

您的查询中还有2个+，THEN部分末尾有1个，ELSE部分末尾有另一个CASE。如果您需要将+表达式与其他字符串合并，请在END之后使用case when FormFields.fieldtype like '%date%' then 'not' + fieldname + ' is null and ( convert(datetime,' + fieldname +',103) < ' + coalesce(str(FormFields.MinDate),'1/1/1900') + ')' + ' or ( convert(datetime,' + fieldname +',103) > ' + coalesce(str(FormFields.MaxDate), '1/1/2200') + ')' else 'not '+ fieldname + ' is null and ( convert(float,'+ fieldname+') <' + coalesce(str(FormFields.MinValue),'-99999999') + ' or convert(float,'+ fieldname+') >' + coalesce(str(FormFields.MaxValue),'99999999') +')' end + 'Any string after CASE expression'。请尝试以下方法：

document.querySelector('.selectable-icons').addEventListener('click', function(e) {
 
    document.querySelector('[contenteditable]').appendChild(e.target.cloneNode(true));
  
});


document.querySelector('div').addEventListener('keydown', function(event) {
    // Check for a backspace
    if (event.which == 8) {
        s = window.getSelection();
        r = s.getRangeAt(0)
        el = r.startContainer.parentElement
        // Check if the current element is the .label
        if (el.classList.contains('label')) {
            // Check if we are exactly at the end of the .label element
            if (r.startOffset == r.endOffset && r.endOffset == el.textContent.length) {
                // prevent the default delete behavior
                event.preventDefault();
                if (el.classList.contains('highlight')) {
                    // remove the element
                    el.remove();
                } else {
                    el.classList.add('highlight');
                }
                return;
            }
        }
    }
    event.target.querySelectorAll('span.label.highlight').forEach(function(el) { el.classList.remove('highlight');})
});
