I have defined below a fragment of an ARM template which creates a service bus topic, subscription, and rule/filter. The rule is applied along with the topic and subscription, but the value of the filter is 1=1. Why would the expression not be applied?
{
"apiVersion": "2017-04-01",
"name": "[concat(parameters('serviceBusNamespaceName'), '/TOPIC-NAME')]",
"type": "Microsoft.ServiceBus/namespaces/topics",
"location": "[variables('location')]",
"dependsOn": [
"[concat('Microsoft.ServiceBus/namespaces/', parameters('serviceBusNamespaceName'))]"
],
"properties": {
"path": "TOPIC-NAME",
"duplicateDetectionHistoryTimeWindow": "00:10:00",
"enableBatchedOperations": false,
"enablePartitioning": true,
"enableSubscriptionPartitioning": false,
"filteringMessagesBeforePublishing": false,
"maxSizeInMegabytes": 5120
},
"resources": [
{
"apiVersion": "2017-04-01",
"name": "SUB-NAME",
"type": "subscriptions",
"dependsOn": [
"[concat('Microsoft.ServiceBus/namespaces/', parameters('serviceBusNamespaceName'), '/topics/TOPIC-NAME')]"
],
"properties": {},
"resources": [
{
"apiVersion": "2017-04-01",
"name": "SUB-NAME",
"type": "Rules",
"dependsOn": [
"[concat('Microsoft.ServiceBus/namespaces/', parameters('serviceBusNamespaceName'), '/topics/TOPIC-NAME/subscriptions/SUB-NAME')]"
],
"properties": {
"filter": {
"sqlExpression": "MessageType = 'TYPE-OF-MESSAGE' AND MajorVersion = 1"
},
"action": {
"sqlExpression": "SET sys.Label='TYPE-OF-MESSAGE'"
}
}
}
]
}
]
}
Your subscription rule should be defined as follows:
"resources": [
{
"apiVersion": "2017-04-01",
"name": "SUB-NAME-FILTER",
"type": "Rules",
"dependsOn": [
"[parameters('serviceBusSubscriptionName')]"
],
"properties": {
"filterType": "SqlFilter",
"sqlFilter": {
"sqlExpression": "MessageType = 'TYPE-OF-MESSAGE' AND MajorVersion = 1"
"requiresPreprocessing": "false"
},
"action": {
"sqlExpression": "SET sys.Label='TYPE-OF-MESSAGE'"
}
}
}
]
I create the service bus filter with the following ARM template, it works correctly on my side. More details we could refer to Create a Service Bus namespace with topic, subscription, and rule using an Azure Resource Manager template
I check it with Azure service bus explore
