Question

@CucumberOptions(
    features = "@target/rerun.txt"
    , glue = {"steps"}
    , monochrome = true
    , format = {
    "pretty",
    "html:target/cucumber-pretty",
    "json:target/CucumberTestReport.json",
    "rerun:target/rerun.txt"
})

public class FailedTestRunner extends AbstractTestNGCucumberTests {}

Answer 1

您可以尝试一下。

CREATE PROCEDURE hochdrei
    @x INT
AS
BEGIN
    SELECT power(@x, 3)
END

请注意，在上述SP中，您会将X值作为输入参数传递给存储过程。

您可以像这样调用存储过程。

EXEC hochdrei 2

结果：8

如果您不想将X作为参数传递，则将在下面使用。

CREATE PROCEDURE hochdrei        
AS
BEGIN
    DECLARE @x INT=2
    SELECT power(@x, 3)
END

将SP称为；

EXEC hochdrei

结果：8

Answer 2

CREATE PROCEDURE Exponentiation
    @Base FLOAT,
    @Exponent FLOAT
AS
BEGIN
    SELECT POWER(@Base, @Exponent) AS Power
END

执行示例：

EXEC Exponentiation -- Result: 4096
    @Base = 4,
    @Exponent = 6

EXEC Exponentiation 10, 4 -- Result: 10000

EXEC Exponentiation 1000, -0.5 -- Result: 0.0316227766016838 (1 / √1000)
