交叉连接与reapitive值

Question

我有一张桌子“Asli”：

while getopts ":a:b:p:u" opts
do
   case $opts in #removed the dot at the end
    a) echo "got an A flag";;
    b) echo "got an B flag";;
    u) user="$OPTARGS"
       echo "$user"
       #double quote the variables to prevent globbing and word splitting
    ;;
    p) pass="$OPTARGS"
    #Passwords can contain whitespace in the beginning.
    #If you don't double quote , you loose them while storing.
    #eg. pass=$@ will strip the leading whitespaces in the normal case.
       echo "$pass"
    ;;
    ?) echo "I don't know what flag is this" 
    #Better double quote to make echo easy, consider something like \\\\\\
    #count the hashes? eh?
    ;;
   esac
done

我插入的值是：

CREATE TABLE Asli(
    clashhid INT NULL,
    TaDah INT NULL,
    DahTaPanz INT NULL,
    PanzTaBist INT NULL,
    BistTaBispan INT NULL,
    BispanTaC INT NULL,
    Marital VARCHAR(20) NULL)

当我通过此查询交叉加入我的表时：

INSERT INTO Asli
 VALUES (1,2,1,0,0,0,'single')

我的结果集：

但我需要更改“已婚”状态0中的值，如下所示：

这样的事情：

SELECT  clashhid,
        CASE WHEN mariStatus = 'married' THEN 0 ELSE TaDah END AS TaDah,
        CASE WHEN mariStatus = 'married' THEN 0 ELSE DahTaPanzEND AS DahTaPanz,
        CASE WHEN mariStatus = 'married' THEN 0 ELSE PanzTaBist END AS PanzTaBist,
        CASE WHEN mariStatus = 'married' THEN 0 ELSE BistTaBispan END AS BistTaBispan,
        CASE WHEN mariStatus = 'married' THEN 0 ELSE BispanTaC END AS BispanTaC ,     
        mariStatus
FROM asli 
CROSS JOIN (VALUES ('single'),('married')) AS custs (mariStatus)
