IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID('T_PostReplyIntervals') AND type = 'U')
BEGIN
    CREATE TABLE T_PostReplyIntervals (
        Id INT IDENTITY(1,1) PRIMARY KEY,
        CertificationTypeId INT NOT NULL,
        PostInterval INT NOT NULL DEFAULT 0,
        ReplyInterval INT NOT NULL DEFAULT 0,
        CreatedAt DATETIME2 NOT NULL DEFAULT GETDATE(),
        UpdatedAt DATETIME2 NOT NULL DEFAULT GETDATE(),
        CONSTRAINT UQ_PostReplyIntervals_CertTypeId UNIQUE (CertificationTypeId),
        CONSTRAINT FK_PostReplyIntervals_CertType FOREIGN KEY (CertificationTypeId) REFERENCES T_CertificationTypes(Id)
