Question

我正在使用此存储过程在我的数据库中搜索名为“Ong”的字符串：

CREATE PROC SearchAllTables
(
    @SearchStr nvarchar(100)
)
AS
BEGIN

    -- Copyright © 2002 Narayana Vyas Kondreddi. All rights reserved.
    -- Purpose: To search all columns of all tables for a given search string

    CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

    SET NOCOUNT ON

    DECLARE @TableName nvarchar(256), @ColumnName nvarchar(128), @SearchStr2 nvarchar(110)
    SET  @TableName = ''
    SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

    WHILE @TableName IS NOT NULL
    BEGIN
        SET @ColumnName = ''
        SET @TableName = 
        (
            SELECT MIN(QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME))
            FROM    INFORMATION_SCHEMA.TABLES
            WHERE       TABLE_TYPE = 'BASE TABLE'
                AND QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME) > @TableName
                AND OBJECTPROPERTY(
                        OBJECT_ID(
                            QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
                             ), 'IsMSShipped'
                               ) = 0
        )

        WHILE (@TableName IS NOT NULL) AND (@ColumnName IS NOT NULL)
        BEGIN
            SET @ColumnName =
            (
                SELECT MIN(QUOTENAME(COLUMN_NAME))
                FROM    INFORMATION_SCHEMA.COLUMNS
                WHERE       TABLE_SCHEMA    = PARSENAME(@TableName, 2)
                    AND TABLE_NAME  = PARSENAME(@TableName, 1)
                    AND DATA_TYPE IN ('char', 'varchar', 'nchar', 'nvarchar')
                    AND QUOTENAME(COLUMN_NAME) > @ColumnName
            )

            IF @ColumnName IS NOT NULL
            BEGIN
                INSERT INTO #Results
                EXEC
                (
                    'SELECT ''' + @TableName + '.' + @ColumnName + ''', LEFT(' + @ColumnName + ', 3630) 
                    FROM ' + @TableName + ' (NOLOCK) ' +
                    ' WHERE ' + @ColumnName + ' LIKE ' + @SearchStr2
                )
            END
        END 
    END

    SELECT ColumnName, ColumnValue FROM #Results
END

我还有一个包含以下记录的表:(从Kondreddi的存储过程生成:)

1 -- Felicidad T.E. Sagalongos
2 -- Bob Ong
3 -- Bob Ong
4 -- Bob Ong
5 -- Bob Ong
6 -- Bob Ong
7 -- Komunikasyon sa Akademikong Filipino
8 -- Book Of Tongue Twisters For English & Students
9 -- Diksiyunaryong Ingles-Pilipino Pilipino-Ingles
10 -- Hong Kong Apothecary: A Visual History of Chinese Medicine Packaging
11 -- A Song of Ice and Fire
12 -- Ang Paboritong Libro ni Hudas

问题是，我想搜索一个特定的字符串，“Ong”，我想要展示的唯一结果是那些写成“Bob Ong”或“Shirley Ong”。我不想出现像“宋”和“香港”这样的词。我尝试使用空格。它给我空白的结果。还有另一种方式吗？

非常感谢。：）

Answer 1

从您的查询的这一部分请删除（％）字符：

QUOTENAME('%' + @SearchStr,'''')

使用Vyas Kondreddi的存储过程在数据库中搜索包含前导和尾随空格的子字符串
