Bonjour à tous, j'ai le script sql suivant pour SQLServer, quelqu'un pourrait-il m'aider pour avoir l'équivalent sous Oracle (11g/10g) ?

DECLARE @state char(100);
SET @state = (SELECT DATA_TYPE FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Interaction' AND COLUMN_NAME = 'IntPlace');
IF 'char' = @state
	BEGIN
		PRINT 'IntPlace is a char DATA_TYPE'
		IF 350 > (SELECT CHARACTER_MAXIMUM_LENGTH FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Interaction' AND COLUMN_NAME = 'IntPlace')
			BEGIN
				PRINT 'IntPlace is smaller than 350';
				ALTER TABLE Interaction ALTER COLUMN IntPlace char(350);
			END
	END
 
IF 'varchar' = @state
	BEGIN
		PRINT 'IntPlace is a varchar DATA_TYPE'
		IF 350 > (SELECT CHARACTER_MAXIMUM_LENGTH FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Interaction' AND COLUMN_NAME = 'IntPlace')
			BEGIN

				ALTER TABLE Interaction ALTER COLUMN IntPlace varchar(350);
			END
	END
 
IF 'nvarchar' = @state
	BEGIN
		PRINT 'IntPlace is a nvarchar DATA_TYPE'
		IF 350 > (SELECT CHARACTER_MAXIMUM_LENGTH FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Interaction' AND COLUMN_NAME = 'IntPlace')
			BEGIN
				PRINT 'IntPlace is smaller than 350';
				ALTER TABLE Interaction ALTER COLUMN IntPlace nvarchar(350);
			END
	END
 
IF 'nchar' = @state
	BEGIN
		PRINT 'IntPlace is a nchar DATA_TYPE'
		IF 350 > (SELECT CHARACTER_MAXIMUM_LENGTH FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Interaction' AND COLUMN_NAME = 'IntPlace')
			BEGIN
				PRINT 'IntPlace is smaller than 350';
				ALTER TABLE Interaction ALTER COLUMN IntPlace nchar(350);
			END
	END

Merci.

Bonjour,

cela devrait ressembler à quelque chose comme ça, attention je ne l'ai pas testé donc il faudra l'adapter, de plus je n'ai pas mis tous les IF car ils se ressemblent tous :
