To solve this, you will have to check &amp; change a locked property. Follow the below steps to do so:<\/p>\n<ul>\n<li style=\"text-align: left;\">Open MS Access database &gt;&gt; right-click the affected table &gt;&gt; select\u00a0the <strong>Layout View<\/strong>.<\/li>\n<li style=\"text-align: left;\">Then, click on a field that is showing the error.<\/li>\n<li style=\"text-align: left;\">Go to the Property Sheet &gt;&gt; click the dropdown of <strong>Selection Type: Text Box <\/strong>&amp; choose the mandatory option.<\/li>\n<li style=\"text-align: left;\">Now, click on a\u00a0<strong>Data\u00a0<\/strong>option &gt;&gt; ensure \u201c<strong>No<\/strong>\u201d is set to a\u00a0<strong>Locked property.<\/strong><\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-67703\" src=\"https:\/\/www.accessrepairnrecovery.com\/blog\/wp-content\/uploads\/2020\/09\/access_form_properties_data.png\" alt=\"Access Database Engine Does Not Recognize\" width=\"380\" height=\"400\" \/><br \/>\n<a name=\"s3\"><\/a><\/p>\n<h3 style=\"text-align: left;\"><strong>Way 3- Check if Query Expression Contains Special Character<\/strong><\/h3>\n<p style=\"text-align: justify;\">Chances are also that at the time of creating the query expression maybe you have used some special character in the field. Thus depending on the particular special character you will receive the following <strong>Access Database Engine Does Not Recognize As A Valid Field Name Or Expression error.<\/strong><\/p>\n<ul style=\"text-align: justify;\">\n<li>If your field name includes a bracket ([]), tilde (~), a semicolon (;), percent sign (%), then you will receive this error:<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong><em>The Expression you entered contains invalid syntax.<br \/>\nYou omitted an operand or operator, you entered an invalid character or comma, or you entered text without surrounding it in quotation marks.<\/em><\/strong><\/p>\n<ul style=\"text-align: justify;\">\n<li>If the field name is having the (?) or (@) special character then you will get the following error message.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong><em>The Expression you entered contains invalid syntax.<br \/>\nYou may have entered an operand without an operator<\/em><\/strong><\/p>\n<ul style=\"text-align: justify;\">\n<li>If your query expression included field name is having a ([]) bracket or parenthesis (()) then you will get the below-given error message.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong><em>The expression you entered is missing closing parenthesis, bracket (]), or vertical bar(|).<\/em><\/strong><\/p>\n<ul style=\"text-align: justify;\">\n<li>If your field name is having a (#) number sign then the following error message pop-up on your screen.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong><em>The expression you entered has an invalid date value.<\/em><\/strong><\/p>\n<ul style=\"text-align: justify;\">\n<li>If your field name is having an apostrophe(&#8216;) or quotation mark(&#8220;) then you will get the below error:<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong><em>The Expression you entered has an invalid string.<br \/>\nA string can be up to 2048 characters long, including opening and closing quotation marks.<\/em><\/strong><\/p>\n<ul style=\"text-align: justify;\">\n<li>If it contains brace ({}), then the error message will be:<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><strong><em>Malformed GUID in query expression &#8216;<\/em><\/strong><strong><em>ObjectName<\/em><\/strong><strong><em>&#8216;<\/em><\/strong><\/p>\n<blockquote>\n<p style=\"text-align: center;\"><strong>Also Read: <a class=\"row-title\" href=\"https:\/\/www.accessrepairnrecovery.com\/blog\/fix-access-error-3167\" aria-label=\"\u201cHow to Fix Runtime Error 3167 Record Is Deleted Microsoft Access?\u201d (Edit)\">Runtime Error 3167 Record Is Deleted Microsoft Access<\/a><\/strong><\/p>\n<\/blockquote>\n<p><a name=\"s4\"><\/a><\/p>\n<h3 style=\"text-align: left;\"><strong>Way 4- Turn ON Cascade Update Related Fields Option<\/strong><\/h3>\n<p style=\"text-align: justify;\">If the query of the table is referring to various table relationships then also you can face the Microsoft Access database engine does not recognize as a valid field name error.<\/p>\n<p style=\"text-align: justify;\">To get rid of it, you can enable the Cascade Update Related Fields in Access.

So just check out the guidelines which you need to follow when working with the crosstab query. This will ultimately help you to resolve <strong>Access Crosstab Query Does Not Recognize Valid Field Name error<\/strong><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h3><strong>Keep it simple:<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">It&#8217;s quite difficult to work properly with the Crosstab queries after a huge increase of rows combination.<\/p>\n<p style=\"text-align: justify;\">So don\u2019t use unnecessary row headings if you don\u2019t need it.<\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h3><strong>Try To Build Your Own Crosstab Query:<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Don\u2019t stick yourself to making use of only Access tables. Start building the totals query after that use that query as record source for your crosstab query.<\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h3><strong>Wisely Choose The Column Heading Field<\/strong>:<\/h3>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Well, it&#8217;s quite easy to read the Crosstab datasheets when the column heading is lesser in number.<\/p>\n<p style=\"text-align: justify;\">After identifying the fields which you want to use for headings. Now it\u2019s time to use the fields that are having very few distinct values for producing column headings.<\/p>\n<p style=\"text-align: justify;\">Suppose if the query is calculating the value as per the gender and age then consider using the gender for column headings in place of age. The reason behind this is, gender typically having fewer possible values as compared to age.<\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h3><strong>Use a subquery in a WHERE clause:<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Make use of the subquery just like a part in the WHERE clause of the crosstab query.<\/p>\n<ul>\n<li style=\"text-align: justify;\">\n<h3><strong>Using Multiple Table In Crosstab Query:<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">For using multiple tables in the crosstab query, you need to make a separate query in which the table is required. Using the <strong>Crosstab Query Wizard <\/strong>you can only choose one query or table for column or rows headings.<\/p>\n<p style=\"text-align: justify;\">To overcome this limitation, you just need to make the query that includes all fields from multiple tables. After then save it in the intermediate query. Later you can use it as a record source for your crosstab query wizard.<\/p>\n<ul>\n<li style=\"text-align: justify;\">\n<h3><strong>Can\u2019t specify limiting criteria:<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">At the time of using the crosstab query wizard, you can\u2019t specify the limiting criteria.<\/p>\n<p style=\"text-align: justify;\">So for this, you can make a cross tab query by using a crosstab query wizard. After then go to the query design for applying up the criteria.<\/p>\n<ul>\n<li style=\"text-align: justify;\">\n<h3>\u00a0<strong>Column Orders or heading issue:<\/strong><\/h3>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">You can\u2019t specify the column orders or heading using the wizard.<\/p>\n<p style=\"text-align: justify;\">To fix this issue, make the crosstab query by making use of the wizard. After that get into the query design and make modifications in it.<\/p>\n<h2 style=\"text-align: left;\"><strong>Alternative Option To Fix Access Database Engine Does Not Recognize Error:<\/strong><\/h2>\n<p style=\"text-align: justify;\">Well, the reason behind this <strong>Microsoft database engine <\/strong><strong>does Not Recognize As A Valid Field Name Or Expression <\/strong>can be a corruption issue. As it is commonly seen when corruption issues are conquered in the Access database then only such problems arise.<\/p>\n<p style=\"text-align: justify;\">If following the above-mentioned ways does not fix your problem, then you can fix it by using <a href=\"https:\/\/www.accessrepairnrecovery.com\/blog\/compact-and-repair-access-database\"><strong>Access&#8217;s built-in Compact and Repair Tool<\/strong><\/a>.
