Microsoft Access tips: DDL Programming Code Examples Examples. Provided by Allen Browne. You can create a Text field, but you cannot set the Allow Zero Length property to No, so any query criteria must test for both Nulls and zero- length strings.

You can create a Yes/No field, but you get a text box, not a check box, since you cannot set the Display Control property with DDL. You can create a Date/Time field, but you cannot set the Format property. DDL cannot create Hyperlink fields, Attachment fields, or the complex data types at all.

Engine(0)(0). Execute str. Sql, db. Fail. On.

Error. For ADO, use:    Current. Project. Connection. Execute str. Sql. Some features of JET 4 (Access 2. ADO only. These queries fail if you paste the SQL statement into the query designer in Access, since the Access interface uses DAO. One case where DDL is really useful it to change a field's data type or size. You cannot do this in DAO or ADOX, so DDL is your the only practical approach (other than copying everything to another field and deleting the old one.) Other than that, Access developers use DDL infrequently.

See the field type reference for a comparison of the field type names in DDL compared to the Access interface and libraries. Here's some examples to get you started if you need DDL. Open Wheel Grand Prix Hacked Unblocked. Option Compare Database. Option Explicit. Sub Create. Table. DDL(). Dim cmd As New ADODB. Command. Dim str. Sql As String. cmd.

SELECT CASE Statement . There are. numerous control statements that turn the program flow based on the.

Such statements are the Select Case. If.. Then.. Else statements, the For. Loop etc. The Select Case statement is the multiway. If the probable actions based on the value of.

It is an easy way. Select Case Syntax: Select Case (expression). It can be more than one value, a range of values or. It can be one. or a combination of the following variations. Case 1)Multiple Expressions(Case 2,4,6)Expression TO expression(Case 2 TO 6)IS < comparison operator> expression (Case IS > 4)The < comparison operator> indicate the. They can be greater than (> ). Duplicate. values are not allowed.

It must be of the same type as the < expression>.< statementx> These are the statements executed when the case constant matches. The value of < expression> is compared with. Case option values. When a match is found, the code sequence. If none of the provided. Case Else. statements are executed. After the statements are executed, the control.

End Select. The Case Else is. Multiple expressions or ranges can be used in each Case. For example, Case 2 To 6, 9 To 1. You can use character strings and variables too. In this example. the statements for this Case option will be executed if the string.
