TSql100Parser.ParseExpression 方法 (TextReader, IList<ParseError>%, Int32, Int32, Int32)
Parses an input string to get an expression. This will return null, if there were any errors.
命名空间： Microsoft.SqlServer.TransactSql.ScriptDom
程序集： Microsoft.SqlServer.TransactSql.ScriptDom（在 Microsoft.SqlServer.TransactSql.ScriptDom.dll 中）
语法
声明
Public Overrides Function ParseExpression ( _
input As TextReader, _
<OutAttribute> ByRef errors As IList(Of ParseError), _
startOffset As Integer, _
startLine As Integer, _

用法
Dim instance As TSql100Parser

Dim errors As IList(Of ParseError)
Dim startOffset As Integer
Dim startLine As Integer
Dim startColumn As Integer
Dim returnValue As ScalarExpression
returnValue = instance.ParseExpression(input, _
errors, startOffset, startLine, startColumn)

参数
- input
类型：System.IO.TextReader
The script that will be parsed.
- errors
类型：System.Collections.Generic.IList<ParseError>%
When this method returns, contains the list of error that occurred during parsing.
- startOffset
类型：System.Int32
The starting offset.
- startLine
类型：System.Int32
The starting line.
- startColumn
类型：System.Int32
The starting column.
返回值
类型：Microsoft.SqlServer.TransactSql.ScriptDom.ScalarExpression
The expression.
