    <p>In my Phonegap Project I need to store an image to sqlite by converting image to base64 string. Image size is 160kb. Image is not getting inserted. Is it because of the size?</p> <pre><code>var encodeImageUri = function(imageUri, callback) { var c = document.createElement('canvas'); var ctx = c.getContext("2d"); var img = new Image(); img.onload = function() { c.width = this.width; c.height = this.height; ctx.drawImage(img, 0, 0); if(typeof callback === 'function'){ var dataURL = c.toDataURL("image/jpeg"); callback(dataURL.slice(22, dataURL.length)); } }; img.src = imageUri; </code></pre> <p>};</p> <pre><code>encodeImageUri('http://static.adzerk.net/Advertisers/030883e15a374ba397b57b8d4bf1033e.png', function(base64String) { populateBannerImage(base64String); }); </code></pre> <p>In populateBannerImage , I m inserting base64 to db.</p> <pre><code>function populateBannerImage(imageData) </code></pre> <p>{</p> <pre><code> db.transaction(function(tx) { tx.executeSql('INSERT INTO banners (id, name , banner_image_mobile, banner_image_mobile_ar, banner_image_tablet, banner_image_tablet_ar,banner_heading,banner_heading_ar, banner_title, banner_title_ar, url, url_ar, status, created_date, modified_date ) VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)',[JSONData.banner_id, JSONData.banner_name,JSONData.banner_image_mobile,JSONData.banner_image_mobile_ar, imageData, JSONData.banner_image_tablet_ar,JSONData.banner_heading,JSONData.banner_heading_ar, JSONData.banner_title, JSONData.banner_title_ar, JSONData.url, JSONData.url, JSONData.status, JSONData.created_date, JSONData.modified_date]); }); </code></pre> <p>}</p> <p>ImageData to db.

    1. CONo! SQLite supports by default [~1GB](http://www.sqlite.org/limits.html) fields. Note you can save raw bytes (in a BLOB) instead of Base64 , saving 25% space. Problem must be somewhere else.

    2. COtype I given is CHAR. First I convert Image uri to Base64 then inserting to db. How to convert Base64 to raw byte. Please see the code....... encodeImageUri('http://static.adzerk.net/Advertisers/030883e15a374ba397b57b8d4bf1033e.png', function(base64String) { populateBannerImage(base64String); });

    3. COSomething is not correct: do you store URI or image data? If URI, why convert to Base64? If data, how do you get it before converting to Base64?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
