我正在使用的SQL Server 2014中有一个如下所示的字段:
<div id="mainapp">
<table>
<thead>
<th>Name</th><th>Status</th>
</thead>
<tbody>
<tr v-for="user in users">
<td>{{user.name}}</td>
<td><combobox v-bind:default="user.status" v-bind:data="status_codes" v-on:item_change="status_change(item, user)"></combobox></td>
</tr>
</tbody>
</table>
</div>
我想添加一个拆分字段并添加一个小数点并创建一个数字字段。这是我想看到的:
var combobox = Vue.component('combobox', {
data: function () {
return {
selected_item:{title:'Select', value:-1},
visible:false
}
},
props:['data','default','symbol'],
template: `
<div class="combobox">
<span class="symbol" v-if="!symbol">
<i class="fa fa-chevron-down" aria-hidden="true" ></i>
</span>
<span class="main" v-on:click="toggleVisible">{{selected_item.title}}</span>
<ul class="combodata" v-if="visible">
<li class="item" v-for="item in data" v-on:click="select(item)">{{item.title}}</li>
</ul>
</div>
`,
created:function(){
if(this.data.length>0){
if(this.default == null || this.default == undefined || this.default =='') this.default=0;
this.selected_item = this.data[this.default];
}
},
methods:{
toggleVisible:function(){
this.visible = !this.visible;
},
select:function(item){
if(this.selected_item != item){
this.selected_item= item;
this.$emit('item_change', item);
}
this.visible = false;
}
}
});
var app=new Vue({
el:"#mainapp",
data:{
status_codes:[{title:'Inactive', value:0},{title:'Active', value:1}],
users:[{name:'Andrew', status:1},{name:'Jackson', status:0},{name:'Tom', status:1}]
},
methods:{
status_change:function(item,user){ //This gets only the parameter from the event. How could I pass the additional parameters to this function?
console.log(item,user);
try{
user.status = item.value;
}catch(e){ console.log}
}
}
});
因此,我需要拆分字段,添加小数点,然后转换为数字值。我尝试了一些代码,但出现错误。请在下面查看我的代码:
**RawField**
20060202
20060323
我收到以下错误:
**RawField**
200602.02
200603.23
这是一个好方法吗?

您要将字符串转换为带有小数点后两位的数字吗?
select convert(decimal(10,2), RawField) / 100.0
我让您的RawField包含其他字母数字,然后您只发布了前8个字符?
这应该有效。只需采用前8个字符并进行转换。简单直接
select convert(decimal(10,2), left(RawField, 8)) / 100.0

请尝试这个。
select top 1000 cast(SUBSTRING(cast(RawField as varchar(6)),1,6) + cast('.' as varchar(1)) + SUBSTRING(cast(RawField as varchar(2)),6,2) as numeric(8,2))
from Table
您正在尝试将带有十进制数字的字符串转换为int。

在投射时使用浮点数/数字/小数
select cast(SUBSTRING(RawField ,1,6) + cast('.' as varchar(1)) + SUBSTRING(RawField ,7,2) as numeric(16,2))
